Its back, but it didnt save my info

This app stopped working all together for me on 1-18-16. Now its working again but it didnt save my info. I mistyped re-entering my info and theres no back button to correct info. AND most annoying if all, I made an in-app purchase to get the water tracker, and I dont have that anymore. It wants me to pay another $1. I know its only a dollar, but the fact is: I paid for it already!!!!
NOT HAPPY.
