This game is amazing-multiplayer needs work

So this game is one of the most addicting and thought inducing games I have ever played on the phone. I am level 70something and the only thing that makes me quit is that I get to the point where I’m on round 260 and the rounds take too long. The multiplayer (co-op through Facebook) is complete garbage. If you get a notification, it disconnects. That is not the phone it is the game because I have an iPhone 6s and the person I try to play with has a galaxy 6 or 7 I can’t remember. Anyways, you can’t pause or exit for 1 second even just out of the app or phone lock and it’s the most frustrating thing ever when you get to round 78 and you are about to start kicking things up and it quites you for absolutely no reason. It’s the worst feeling in the world and extremely annoying/aggravating. If you guys can make this better, that would completely perfect the game and make it the very best game on mobile for a very very very long time. Thanks :)
