I have a PIN entry screen where there is a numeric keypad made of buttons. But there is a lag time between the button press and the button being available for being pressed again. If the user is trying to enter a PIN of 2222 then they will be trying to click the same button repeatedly, and most of the clicks will be ignored because they are during this lag or recovery time.
Demonstrated here (just try clicking the button repeatedly and see some get skipped):
Any ideas for a workaround?
