Nu zice de nici o limita, cum e la PS4:
You can enable Console Sharing and Offline Play on one PS5 console at a time. If you enable the setting on a new PS5 console, the Console Sharing and Offline Play setting on your other PS5 console will be disabled. Other users on the disabled console won’t be able to play your games and media.

PS5 Console Sharing and Offline Play does not affect your primary PS4 activation limit.
