I mostly play the game on mobile. I use Hive Keychain browser on android phone to access the game. After the 'Mobile click functionality improved on links with popovers.' change I'm not able to click on the upgrade links. Whenever I tap on the buttons, the help popovers open. There was no such problem before the change. Please look into this matter ASAP.
