New issues after years

I have been using this app for like 4 years now. All of the sudden the app rest and still hasnt gotten back on track with my cycle. I restored from backup and gave the app 3 months to catch on itself and it still hasnt. Now Im having to count the days and keep up with it myself...kind of eliminates the point of having an app to track my period. Hopefully this issue is resolved soon. I never had a problem until a few months ago.
