[2019] Heavy lag issues - any ideas ?

So, since the "get rid of toaster phones" update i've been encoutering a pretty weird lag issues.

Many reinstalls, cache clears... nothin' worked.
Galaxy s7, 8.0 android.

Basically, if i go out of the game but let the app run, when i come back, if i start a fight, it'll be laggy as HELL. Whatever the fight, whatever ships or toons.

Restarting the app DOES solve the issue; But having to restart the app on my phone every time i want to check discord is becoming really old really fast.

Any ideas of what's happening ?

Any guys around with the SAME ISSUE ?

( plz, don't comment if you have any OTHER issue to solve, there is other posts for those issues ... or just create your own... )
