I've had this problem too but the latest upgrade just fixed it. And yeah, I think it was Google's doing and it's not the first time, it's a constant arm's race between them and Newpipe programmers. And Ublock programmers. And Invidious and Piped programmers etc...
I did that yesterday, didn't fix it. I was able to got the update from Newpipe directly today but my Boo had it three days ago, he said he got it from GitHub? No idea how to do that but maybe worth a looksy.
They've decided to step up the arms race because they've hit peak daily user count and the only thing they can promise to the board is force increasing premium memberships. I take it channel "memberships" are also not hitting the numbers they would like and they haven't destroyed Nebula or Patreon as they'd hoped.
I will never pay for YouTube. The most they'd do is force me to stop using it. I'd be fine using the mobile site, but they've gone and intentionally broke that too. I mean, it works, but it's buggy as shit.
It's not working for me. I just uninstalled and reinstalled, but no luck. PipePipe works, but it keeps pestering me to enable notifications, so I uninstalled it.
