I used a temporary phone number website for one of my instagram accounts and the people/bot from the website changed all the profile information, i was still able to get it back with my og email even though it happened every few hours untill "they" just gave up. That got me confused on how emails workIf the Buyer changes the Email,Email's Password,Enables 2fa for Email ID,Instagram's Password,Unlinks any Facebook Account/Page if any,Changes/Removes Phone Number with his own one and enables 2fa,Seller cannot get it back again.
