When I log details into my menstrual health, I save, the screen goes blank and I am directed back to the main page of the app. I go back into the MH section and the details didn't save. I also do not see any of the data that I had previously entered, so I have no idea how long this has been going on. I was able to change the date of my period though, and that actually saved.
My app (Android) is up to date, I force stopped it and cleared the cache. The problem persists.
