Why are you posting in caps (basic etiquette).
There are many gameplay issues that have been raised recently, and there is no known update.
As for cheaters, if you believe someone is cheating, report them in-game.
Regarding your devices and lag, there are two possible problems.
- One is the current latency issue that has been present since the Anniversary event launch.
- The other is your internet connection. If three devices have the same latency problems (a massive hint here), does it happen when you are at another location, for example, the friends you mentioned? What happens if they play at your place? What setup do you have, such as connection type, wifi setup, whether you use mesh, and whether this also happens on the mobile network? What speed test results do you get on your computer compared with your wifi?
Network and lag issues are always hard to solve as these could be your end, your provider, network carriers or EA, but you do need to rule out your own setup first. Most users rely on basic default setups without looking at signal propagation (horizontal vs vertical, etc) and channel overutilisation (especially on 2.4 GHz spectrum).
