Bug problems
I usually love this app. But here lately I’ve been having issues with the app. It closes automatically or doesn’t put when I end. It tries to override what I save. I can’t even open the app now. It keeps closing on its own. I tried to write to the app support but it’s not letting me. App itself closes real fast before I can take a screenshot of my period tracker dates. I even had issues looking for the app on App Store. When usually I can find it fast with no issues. I would at least like to screenshot my menstrual cycles so I can get a different app. Very disappointed because this app was my favorite one. Now I have to try out new ones.
Big problem App will not stay open
I go to open the app and it closes on its own. Never has there been any issues and I’ve used the app for years very
Keeps shutting down
