I was playing today and after logging back into the game, my account simply disappeared. I noticed that the game was not linked in the Play Store and needed to be manually linked to an account. I ended up not linking, unfortunately. And I would like to recover my account, since I wouldn't be excited to start another one again. I believe it was my mistake for not paying attention to this, but I can provide the necessary information to prove that I had the account and link it in my email.
