Mac to PC issue?

Hi everyone. My friend and i recently downloaded this game because we saw it could run smoothly on a mac computer. We both have the game installed and can play against other players and the computer. But when we attempt to befriend eachother it wont let us. Is this issue because I am running a mac client and he is on a pc?

We’re aware that this is currently an issue, and should be resolved in the next patch (due in the next few days). Thanks for reporting your issue.
