Hello dear developers! 

Previously, in order to play together on android in Minecraft it was necessary that one smartphone handed out, and another connected. Now this will not roll, and it is necessary that both smartphones were connected to Wi-Fi. It's not good if you're away from the nearest Wi-Fi and you want to play with a friend. You hand it out and it connects, you enter the world, and the inscription about the lack of connection to Wi-Fi is highlighted. Why you did it, if before everything worked and with the internet from the phone, it is unclear.

Forgive you to fix it and give you the ability to connect through the access point from your phone. Thank you for your attention!

Add: I added a screenshot (it's on Russian, it says that to play with friends you need to connect to the Wi-Fi network.
