I invited my brother to play hearthstone. He plays on pc and im on mobile. I wanted to Add friend with him but it seems like i cant get his friend request. I have sent him a friends request too. And he has me on his friends Tab but it says im away for x (time). Yet his account doesnt Show up on mspeed testy friends list. Please help me. showbox
Hmm did you maybe accidentally start playing on different zones, for example EU and NA? That can lead to you seeming offline.
Another thing that might have happened, I vaguely recall I once collapsed my friend list or something and so could not see friend requests and whatnot. See if you can click any arrows on your friend list to expand it.
Finally consider adding each other as Real Life friends, ID, however that thing is called. That might open the lines of communication.
