I apologize for not getting back to you sooner. I have Roku firmware version 10.5.0 build 4208-91 and YouTube version 2.21 build 94005088, and I still have this problem. Is there any way this can be fixed?
Please be advised that channels on Roku are developed and maintained by the channel developer themselves. We suggest reaching out to YouTube's customer support team to see if they have any additional settings or options within their app that may resolve the issue you're experiencing.
