I think I've had issues before where YouTube refused to play videos at all while I had my AdBlocker blocking the ads. Not sure whether it was intentional.
No, not just you,
I’ve had the same problem, and I have youtube premium. Though it’s not consistent, sometimes it works, which makes me think that it might be related to some choice of the content creator.
YouTube premium you say? Grab yourself a free Stadia controller: https://stadia.google.com/SdFGljSduV5z
It was fixed in the first Release Candidate. Are you running the latest version?
Is this just me or anyone else?
