I have ASIA PS+ account activated on my PS4 but i use my US PSN account to play online.

Funny thing is that every time i turn on my PS4, i can't straight away play online mp with my US PSN account. I must enter my Asia PS+ account and activate it on PS4 again, then can go back to my US PSN account to play online. This is extremely troublesome.

Anyone knows the workaround?
