Not working!!’ – Productive - Habit Tracker Review

I’ve been in a 75 day challenge with friends and I was on day 66 when the app said “working on update” never opened or closed abruptly! When it finally gave the option for passcode it stated on the screen and never opened!!’ I cannot get to all my data now. What can I do to have this fixed?
