Division rivals (local co-op)

Just wondering I have i ps5 with fc25, I have ps5 plus in my log in. Tried to start a local co-op with my friend to play rivals online but it didnt work.

just asked his log in for the controller to sign up for ps plus? Do every controller need a separate ps plus subscription?

This must be a bug or does the greed have no limits?

For me to be able to play local co-op with friends in my ps5 need multiple psplus subscriptions?

this truly is a dealbreaker for me the only time i play is with friends?
