Justin the problem is with your network as you say that it happens both in phone and pc.
Local area network has limited bandwidth.So if there are more users who are printing or using softwares at same time,then it may happen that your network starts to think that you are inactive if you will does not respond to it.
Dont open more than one tab in browser and restrict background data in mobile version.
Keep on tapping and switching your device where you play t11.If you get idle or not touch screen for 15 seconds.Network may think you as inactive lol
My friend had same problem ,,nothing to do with phone but still you can improve better experience in pc version.
I will share it later,,,so you can atleast enjoy pc version.
