When switching from one YouTube TV channel to another I am frequently getting a licensing error message that I never see on either my Sony TV's app or on the Nvidia Shield app. The error even shows on the same channels that were working two minutes earlier. I don't remember this problem on my older Roku Ultra, just since I bought the 2020 Ultra for its Dolby Vision and Atmos features. I've tried removing and reinstalling the YouTube TV app but the problem is still there. Basically I have to shut down Roku and restart for this app to work for a while.
