This might work , it worked for my android device, I think sometimes the update does not install correctly messing it up -1) Uninstall the Champions app2) Go to store and install the game.3) Restart the phone.4) Open the game, login to your account and play.
Same here - dexterity got worse after the update, especially in the fights against more difficult defenders (AW Boss in my case).I haven't noticed any changes regarding parry after the hotfix - the bug still happens from time to time.
