Hot spot play issues

Hi there. I have a problem with joining to my friend's world. In version 1.8 we're playing together in his world using hotspot, but when I update the game to v. 1.9.0.5 and later to v. 1.10.0.3 I just can't connect to his world, and he's has the same problem. We both playing at the same versions, but game just don't see opened world in other devise. 

Can I fix this or just must waiting for full realised? Thanks.
