Hi @De100,
Greetings and welcome to the Roku Community!
We understand your concern with channel issues, and we're here to assist. Kindly follow the steps below to resolve the issue you have encountered.
- Navigate to the channel tile on the Roku home screen, press the star (*) key on your remote, and choose "Remove channel".
- Next, restart your device from Settings > System > Power > System Restart (If you do not see a Power submenu, skip to the next step).
- Once your player/TV starts up again, go to "Streaming Store" on the Home screen, and add the channel back once more.

We hope this works.
All the best,
Kash
