Main causes of Funimation App Not Working On Vizio Smart TV

There could be a number of reasons including:

• Outdated App Version: The most common cause of the Funimation app not working on Vizio Smart TV is an outdated version of the app. To ensure that your Funimation app is working properly, make sure you have the latest version installed.
• Low Internet Speed: If your internet connection is too slow, it can cause the Funimation app to become unresponsive. To ensure that your internet connection is fast enough to stream Funimation, connect your Vizio Smart TV to a faster internet connection.

How to resolve Funimation App Not Working On Vizio Smart TV ?

Fortunately, there are a few different methods you can try to get Funimation working on your Vizio Smart TV again. 

1. Check Your Internet Connection

You may experience buffering issues with Funimation and other video and streaming apps if you have slow internet. In extreme cases, your internet may be too slow or unreliable for you to even connect to the Funimation servers.

You can conduct an Internet Speed Test on either your computer or phone. Ensure the device you are using is connected to the same network as your TV, turning off mobile data and connecting only through Wi-Fi when using your phone. 

If your speeds are slower than the recommended 3–4 Mbps for standard streaming and 5–8 Mbps for HD, you will need to take the below steps:

• You should investigate any potential sources of interference, like too many walls between your router and your TV. 
• You should also restart your router.
• Contact your internet provider to determine if there are any network issues or if you need an upgrade.

2. Restarting Your Router to fix Funimation app issues

Routers are the backbone of your home network, so if your Funimation app isn't working properly on your Vizio Smart TV, restarting your router may be the solution. 

Restarting your router is a simple and quick process that can help resolve many common network issues, such as slow speeds, spotty connections, and even Funimation app not working on Vizio Smart TV. 

Here's how to restart your router:

• Start by unplugging the power cord from the back of your router and modem.
• Wait 30 seconds and then plug the power cord back into the router.
• Once the lights on the router are back on and steady, you can turn on your Vizio Smart TV and try using the Funimation app again.

Restarting your router may temporarily improve your speed, but it won't solve the issue that is causing the problem.

3. Restart your Vizio TV by power cycling it

Power cycling your television can help reset the network connection and clear out any temporary glitches that might be preventing the Funimation app from working properly. 

Here's how to power cycle your Vizio TV:

• Unplug your Vizio TV from the power outlet.
• Wait for at least two minutes.
• Plug your Vizio TV back in and turn it on.
• Wait for the TV to boot up and then launch the Funimation app.

Power cycling your Vizio TV should help resolve any temporary issues that are preventing the Funimation app from working properly. 

4. Ensure Your Vizio TV Is Compatible With Funimation

In order to use the Funimation app, you will need to have a Vizio smart TV model from 2016 or later, as these models run Vizio's SmartCast OS.

You can determine the year of your Vizio TV by accessing the model number from the TV's system menu or finding it on a sticker on the back of your TV. 

You should note that the model number will be something like V60-K2. The last letter of the model number will tell you the model year; D stands for 2016, E is for 2017, F represents 2018, and so on.

If you have a Vizio TV from before 2016, it's best to choose between either replacing the TV or adding a streaming stick as the cheaper and easier option.

You can easily watch Funimation on any TV (smart or otherwise) by adding a Fire TV Stick or a Roku streaming stick. Both of these streaming sticks are easy to install and use, and provide access to all of the major streaming apps.

5. Update Your Vizio TV Firmware to fix app issues

Updating your TV's firmware will ensure that your TV is up to date with the latest software and that the Funimation app is compatible with the device.

To do this:

• Press the V button or the home button on your remote.
• Select System from the menu.
• Press Check for Updates.
• Wait for your TV to check for updates.
• Confirm the update installation if one is available.
• Once the update is complete, restart your Vizio TV. This will ensure that the new firmware is in effect. 

After the restart, you should be able to use the Funimation app without any issues.

6. Clear the Funimation App Cache

You may not be able to upgrade or delete apps on your newer Vizio TV, however, you do have the option of clearing an app's cache.

This is quite similar to clearing the cookies in your internet browser, and often it will solve random glitches in the app.

To do this, follow the below steps;

• Press the V button or the home button on your remote.
• Select System from the menu.
• Go to Apps.
• Click System Apps.
• Select the Funimation app.
• Click Clear Cache.
• Press OK.

Now, Give the Funimation app another try.

7. Disable Your VPN

If you use a virtual private network (VPN), this step is relevant to you. If you are not familiar with what a VPN is, then you are likely not using one.

You should try and test your connection by turning off the VPN, as most video apps and streaming services attempt to block VPN traffic. If Funimation has managed to block your selected VPN, you will likely not have access to your streaming content. 

8. You may want to consider trying Funimation on another device

You can try opening Funimation on your computer or any other device on your network. 

If Funimation works on your other devices but not your TV, then it's time to reach out to Vizio support. 

However, if Funimation isn't working on any of your devices, the issue may be with your Funimation account or with Funimation's servers.

9. Inspect Funimation Server Status

If you are having problems with Funimation, you can use Downdetector to see if other users in your vicinity are also experiencing the same issue. In most cases, these outages are isolated and can be fixed quickly.

If you have not been able to locate anything on Downdetector, it is recommended that you contact Funimation support for more information. 

10. Perform Factory Reset to Your Vizio TV

A factory reset is a process where all of the settings on your device are reset to their default values. This can be a great way to fix a wide variety of issues, including problems with Funimation. 

Here's how to perform a factory reset on your Vizio Smart TV:

• Press the V button or the home button on your remote.
• Select System from the menu.
• Go to Reset & Admin.
• Click Reset TV to Factory Defaults.
• Enter the parental code password. This will be 0000 if you never set it elsewhere.
• Press Reset.
• Wait a few minutes for the TV to fully reset and come back on.

After performing the factory reset, you can now try to open Funimation again. You may need to re-enter your login credentials and set up the app again, but it should now be working properly.
