I am playing on iPad Air 2 with the latest iOS update but everyone in the lobby seemed to be having the same problem.
In the lobby it started with people's chat overlapping each other. Then people started switching usernames. For example when I chat it showed up as Fanta1 when my username is codexannihilatex. Another problem was the game kept glitching between showing 1 host, 3 hosts and no host. Also several people with the same name kept joining. (pyromonkeyGG)
Besides that the game just crashes right after I find out my role.
P.S. I wish people who play on their phones realize BETA does not equal playable and you guys are trying to actually make the game to be the best it can be. BETA = we help you make the game playable for your target audience on your target platforms first.
