Activating PS4s as primary

I gameshared with my friend and it worked however, him and I wanna play the same game together online. I want to use my account which is the one I used to gameshare with him, and he wants to use his own account that he downloaded the game I shared with him and I know that him or I have to activate the account as primary for the PS4 system in order to play the game.

My question is, can we both activate the same account as primary and play the same game simultaneously?

Solution 1:

On the official page they specifically state you can play multiplayer on local but not online: https://www.playstation.com/en-gb/explore/ps4/features/share-play/
