ok - since I have 2 Roku 2 boxes that were updated on the same date - 11/17/21, I plugged the other one in and it does the same thing. After a night left alone, it needs to be rebooted.
I have the same problem and have tried every solution under Fix Your Remote. Does anyone at Roku have a real solution to this problem that apparently was caused by the latest update? Don’t need brush off responses from Roku
