I have two accounts in spotify one is premium and the other one is free. I accidently lot out in my premium account and when I tried to lot in again it said there isn't an account name like that but then I confirmed with my free account and my account name is right why is spotify giving me this warning

Hey @alzefe, welcome to the Community!

We suggest you follow the steps listed here to see if you can find the usernames and email addresses tied to both accounts.

Once you've got that sorted, you can close the Free account following these steps.

We hope that helps.
