How often can I active/deactive primary PS4? I have 2 PS4s in my house and need to switch constantly.

Hi everyone,

so I have my PS4 in the living room and my GF's PS4 in the bedroom.

My account has PS+ and hers doesn't. She can only play online on her account if the PS4 is set as primary.

Currently my PS4 in the living room is set to primary, and today I would like to make hers primary so she can play online in the bedroom on her PS4 using her account.

Will there be some kind of time limit as to when I can switch the primary back to my own PS4? Is there something I should watch out for? Or can I switch back and forth constantly without problems?

Thanks!
