Probably to sadly close 'another' Google service, (YouTube Gaming), because most do not care about quality (like our Google+ days) and have mostly gone with low quality, insecure and broken Twitch 😒

This is caused by account switching applying across subdomains. I had a chat with a help person after bugging them on Twitter: https://twitter.com/qwallis/status/1136607566899949568

It will get fixed apparently. Which is good because without a fix YouTube Music is pretty much useless to me and anyone else who's switching between brand accounts on YouTube.

Well... mine was for YouTube Gaming, but that is now officially dead, so... Thanks (again) Google 🤮

...hopefully Gòógley fix it for you shortly though 😘
