Lots of lag time in the game

Same situation friend , loosing crystal in G.Arena & Fleet battles .

Thanks, I will give it a try

Most of my guildmates who use Android are experiencing terrible freezes after the update — in Grand Arena, Territory War, and Fleet Battles. I lose crystals every day because all 5 out of 5 battles freeze. I lose crystals because the game hangs during Grand Arena.  I sympathize with you, my friend.

Although not a great solution, if you have a PC with SWGOH installed, the lag is non-existent. I just beat an Exec in a normal timeframe with my Levi. Just make sure you enable the 4x speed, if you're used to that.
