Since the upgrade 21.6 I’ve noticed multiple problems with the game.
Touch screen being very unresponsive at random points when shooting darts.
Chests taking 6 to 12 taps to open.
game not responding in middle of battles with both other players and when fighting incubator events.
These issues really need to be resolved. The upgrade to 1.6 definitely improved the fun of the game, but the stability issues take a lot of that away.
