YoutubeTV source drops

recently (within last week or so)
i noticed on favorites channels were missing
short investigation saw my youtube tv source was missing? i thought that odd and added as a source and all chanel’s were back as normal.
now it’s happened again? this is not a login error but the source actually is no longer listed (using windows pc platform) so i will add it again… is there some issue with update of
channels?

Have you looked through the logs to see if you see any notable errors? You should also send a diagnostic log from the server to the devs, if it's an isolated case, may take a while to get attention, but if it's also a new bug that starts to materialize more, better that they have the logs to see what they can observe from the log info.
