I use an Galaxy S4 an iPad 3 and on a Pc 2 android emulators. In all 'devices' after a couple of minutes the messages in gc/zc stall and are not refreshed. I have to restart game every time to see a number of sometimes important messages i've missed.
I've mailed customer service but they are blaming my hardware/free memory.
Also i was told that not many people where having this problem, but i've read it some have same problem too.
If it is true that all my devices are not suited for the game, then you should adjust your programming or provide a simple refresh button. This is a basic function and it is really really annoying that it is not functioning properly.
