I was trying to use my wife’s phone yesterday in my failed attempt at top 5’ing the deadpool pve and thinking I just had to link my Facebook I clicked on it but it linked her Facebook to a new account. I tried to uninstall, reinstall and then log myself into Facebook but that didn’t ever work. Anyway now I get my wife popping up as someone to send rewards to when she’s not actually playing the game so I’d like to be able to delete the link between her Facebook and MPQ. Anyone know the best way to go about this? Thanks 
Mohio, you may have to shoot an email to customer service. The should be able to unlink the account.
Go onto her facebook, click games, click the tab that says “your games”. Remove app there. You can do the same if you want to change which facebook account your MPQ app is linked to.
