It seems to connect, but then all you see in the dev app is an empty skybox. No parts, no player, no nothing. The app was working about a month ago when I last tried but it isn’t right now.
Repro place not needed as this happens with any of my games or even a brand new place.

Edit: Also there are tons of UI-related bugs in the app with texts like it saying “RbxDevWaiting”, “PairWord”, “RbxDevPairingInstructions”, and other stuff similar to that.
This is probably because the Developer app is still on 215, while the client is currently 221. I believe there’s at least 1 breaking network/replication change between those version (if not more). Developer v222 will be submitted this Wednesday, and hopefully approved in the next week. Sorry for the delay, it should have been updated more regularly.
RE Developer for Android: No promises/release date estimates, but I believe it’s on our 2016 mobile road map.
