After the update on a Bluestack Nougat 32 bits emulator with 2GB of RAM and 1 CPU core, the game was launching but crashing very fast (depending on the actions but usually in less than 3 minutes). It was playable before the update. I had to upgrade the emulator to a Pie 4GB of RAM 2 CPU core to have a stable game.
Which probably means that the latest update significantly decreased performance.
