I had 20+ Pokémon on my Pokémon GO account, and today, when I tapped on the app, it brought me back to the original screen when you first start playing.
My friend, who signed up, tested using my username when she first started, and my username was unavailable, meaning the account still exists. I don't have the password for the account, but I do have the email. Is it possible to log back into the account?
