I have read this: https://community.playfab.com/questions/61570/deleted-title-player-accounts-but-master-player-ac.html
But it does not answer the question entirely. We got bombarded with 100k+ logins. We had to create a new title and remove the old one. Now, players are not able to login to the new title because it says, the email is not available.
I can't see any master accounts related to the old title in the new title. YET, it is using that information.
Players don't remember their login. How do I send reset password? How do I delete master accounts I can't see? I need to free up these emails. Specially when testing, we are trying emails to figure things out. But is very inconvenient to not have all the data.
What should I do to find these lost Master Accounts? Or is there a way to remove the master accounts even though I can't see them?
