Has anyone been able to resolve this issue? It's baffling.

If I try to reset my passowrd for the account with that email, it says no account with that email exists. If I try to create an account with that email, it says that email is already linled with an account.

It's important to me that I be able to have my music Instagram linked with the email I use for music.

I am very confused. Has anyone else had this issue? If so, were you able to resolve it?
