Hi there! I tried to change the email address on my account, and for some reason it created a new account under the new email address?
All you'd need to do is sign into that new account, and head to the settings page, under Account, and change it's email to something random, then Delete My Account.
Then sign into your correct account and do the same for changing the email, under Account. Is that where you went to change your email address?
When the error happened, I had gone to account settings to change my email
address on the phone app.
