Password/Username is "wrong" after premium upgrade

[user-removed]

So I had been using spotify through my Facebook account. But just got a premium account through my Gmail account. Spotify will let me login to the Facebook associated account but will not accept my username or password for the premium (Gmail associated account) . So I've been paying for the services for about two months, but haven't been able to use it once.
I've tried uninstalling, logging in and out, I even got a new phone and it still won't work on my new phone.

Hey @user-removed,

Can you please send me a screenshot of the error message?

Thanks!
