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 will try this. Great answer and explanation as to why might be an issue. I thought on my older Roku TV that it had an option to clear cache because I was thinking might be something like this. I like your suggestion to delete some older unused tiles/channels to try and free up a little memory. I hope it works for me.
I Have a Sharp Roku TV model # LC-43LB371U Manufactured April, 2015. I have had the same problem with Amazon Prime video icons being blank when I open the app. This has happened several times over the past year or so. I followed the suggestion to do a system restart on the TV and it worked. Sometimes restarting my Xfinity cable box has helped but not always. This time I went to the Home icon on my Roku remote then: SETTINGS -> SYSTEM -> POWER -> SYSTEM RESTART. When opening the Amazon Prime App, it took a few seconds but the icons came back.

This happens frequently, and to many users. Don't you think maybe you should FIX IT?????? So frustrated. May you have toddlers who want to see the icons and have to reboot and uninstall and reinstall so you can know that this is a PAIN IN THE **bleep**.
