I am having the same problem and your steps did not solve it.
Hi, Baenwort.
We appreciate the efforts you've taken to troubleshoot the YouTube app on your Roku.
If the issue persists after doing so, we highly recommend directly contacting the channel provider for further assistance, as they manage and maintain their app on the Roku streaming platform independently.
You may reach them here: YouTube Support
We hope it will get sorted out soon and appreciate you bearing with us in the meantime.
Best regards,
Carly
Suddenly Youtube is back to the way it was, no longer asking me to sign in.
I have no idea why, but it is back to normal, and I did nothing.
