Ah. Yeah I'm the only one using my instance. Haven't had that issue.
Once piped stops working for me YouTube is dead to me. I had to load up a video at work the other day using the YouTube website and holy crap is it naaty looking these days. Can't use any browser extensions at work so ads and crap everywhere.
My selfhosted instance is still working. I'm the only user which probably helps it from getting flagged. If they manage to kill Piped and the other similar options, YouTube is dead to me.
