I tried to search for an awnswer but couldn't find it so far :(

I really like Gods Eater Burst on the psp so I bought it for my vita and wanted to coop with my girlfriend. But I can't seem to find her in the lobby. Does anyone has a solution to this? Or is it because it's not crossplatform compatible?
