Hullo.
I just started with HA and looked at the Music Assistant Addon and the Youtube Music instructions. I followed the instructions, found that I needed the beta to work. Got that working and was thrilled with it last night. Woke up this morning to both Youtube Music and Youtube not working in my account on any platform. I had a chat with YouTube support and they said my account had been suspended due to suspicious activity. It’ll reset itself in “A few weeks”. Anyway, not much I can do about it. Just my experience.
