Every once in a blue moon one (or more) of my virtual channels is suddenly "empty", as in nothing is scheduled or playing. If I try to play the channel, it just shows an endless progress spinner.
The On Now image is replaced with the channel logo:

And the Guide is empty in the app:
...and on the web:
When I check back later (not sure of exact duration since I usually forget about it, but definitely a matter of hours) the channel is populated and working again. This has been happening since virtual channels were released to stable, and is still happening now in 2022.02.09.0020. Anybody else seeing similar behavior?
