Since I started playing Neomonsters on my android tablet (SM-T700, android version 5.0.2) around a month ago, I haven’t been able to play a single pvp match. It loads for a sec or so and then it fails to connect (“could not find opponent” message appears). I’m not sure if I’m the only one having this issue, since the other online activities work just fine. I’m sure that my ISP and wifi connection works fine, 'cause I can play without problems in my iOS account and iphone 
If you have the same problem, or similar, please let me know if you found a way to fix it, and share your phone/tablet model and firmware version so the devs can take a look.
Thanks
