Hi @KUSKUT,
Welcome to the Roku Community!
Thanks for letting us know about the fast-forward function issue on your channels. We'd like to look closely into the issue.
Before we proceed, could you please provide us with more details regarding the issue with the fast-forward function? Does it not work when you press the fast-forward button, or is there something else that happens when you try to fast-forward the show on these channels?
We look forward to your response.
Thanks,
Riamie
