Hi @AnnetteMich,
Thanks for joining us here in the Roku Community!
We appreciate your report about this playback issue you're experiencing, and we'd like to help. Could you tell us when did you start seeing this?
In addition to the troubleshooting you've tried. Try this pattern instead: Remove, Restart, and then Reinstall. Or you can refer to our support page here: How to resolve a channel playback issue
Let us know if that works.
Thanks,
Rey
