Cannot unlink PSN account from Activision. : modernwarfare
If you try to open a private navigation tab with Chrome, go on the Call of Duty website to connect in your activision account, then go to the link page, you should be able to try ( at least) to connect or unlink the account either you need to unlink or link your account(s). For me I tried to link my psn to activision but i get the same error as you guys.
