When I first created my app I redeemed my developer test flight code on an old Ipad with a Test apple ID account. I need to revoke that test flight and associated with the correct apple id on a new Ipad.
Every time I delete and try to re-add my email on testflight it keeps its same association with the wrong Apple ID.
My email is with one Apple ID, but the same email is associated with a different Apple ID in testflight.
