My friend has a ps vita, while i have a ps3. Whenever he and i are online at the same time, it never says hes online on my friends list. I dont know why it does this but i would assume its cause hes using a vita while im using a ps3. DOes it have to be this way because its really annoying that i can never see when hes online from my ps3.
I have friends that I invite to play versus matches right. When I check on PASBR by clicking R2 they are there & I can send then an invite. BUT when I check on my friends list they are no where to be found on the Friends Online. Hope this helps, once your at the versus menu you can check if he's online
