I have been playing this game for about a year now and I have switched devices in between. However, as of now my game doesn't seems to be linked to a Kabam ID.

Also, when I am trying to login into the account with the email that I know might have been used to create the account, I am getting a message saying that account is already linked and do you want to login with this account.

When I link my account, my game progress gets lost and it starts from the very beginning at Level 1. At that point of time, I have to delete the game and then install it again. Once I install the game again, I choose not to start a new game to restore my game to the progression that I have made into it.
Can anybody tell how can I link my account to a Kabam ID ?
