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.
Since Fyre TV isn't in the Channel Store, you're using what Roku calls a "non-certified" app (or channel). That means Roku doesn't support it.
However, there are some tips regarding apps in general that might help. When an app misbehaves in the manner you describe, removing and reinstalling it may help. Be sure to perform that this way, all three steps, in this order:
Remove the app
Reboot the Roku
Reinstall the app
Try that and see if it resolves your issue.
