Can both of you guys log in to AMD Rewards on a regular computer?
Hello I can log in, but it asks for verification code as soon as I do.So I can access my account.
Now the cellphone has no issue since I get texts from steam,ms,bz launchers
They have activated the account but now I have to again contact them through support for code activation as it doesn't allow me to proceed after entering the code.
