Apple Music is not using the Apple ID I am logged in with
I have a brand new Macbook Air M2 13.6" 2022. I am logged in with the Apple ID I have been using for years, on my iPhone and iPad.
However, when I launch Apple Music... it uses the Apple ID I lost around 20 years ago. I can see content from the old lost apple id, but I cannot play it.
The instructions I found via google on these forums from 2012 say to log out of the old ID - one, i lost it decades ago and thats why I have a new one, and even if I did... log out where? All three of my Apple devices are logged in with the new ID.
Help?
