Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
I've tried all of these fixes and for me they are only temporary. Eventually it comes back missing thumbnails and wording gone once again. Unbelievable that this hasn't been fixed yet and it looks this may be my last TCL/Roku TV!
This Worked! Thank you so much!! I tried looking up what to do on youtube, nothing helpful, wasted time watching videos. I had already uninstalled the amazon prime video app, and reinstalled, nope. Then I unplugged. waited at least an hour, because I was busy. Unplugged the TV not the modem, just the TV. All the thumbnails on the amazon prime video are all showing now 🙂
Thank you. I'm having the same issue and I'm going to try this. If this works, I would suggest putting your response and others like it (unplug the TV for five minutes as it apparently forces a hard reboot/update of all tiles) as the preferred/first answer instead of Tanner D's more generic response.
