I want my friend's account to be more active on my console as primary, but his account is not linked to primary on any other ps 4 and still nothing can be done?
Maybe because your account on this PS4 is also primary?! Only 1 account can be primarily connected per device.
So yo want yours to be premier
Everything is over
So he has to do it himself on his ps4 in your acc. Btw can primarily activate up to 3 people, you and 2 others. If only one can turn on, you can primarily turn off every 6 months on all devices in your acc. By then at the latest, 2 people should be able to switch on primarily
