My Question or Issue
When I'm on my account, my name is alphanumeric, but I don't use Facebook, and it's been that way for almost 24 hours
Hey @Spade_Tsunami, help's here!
That's normal, since Spotify automatically generates usernames. It's currently not possible to change your username - and there is more info on this here.
I hope this helps ;)
