Data all gone?!

Abbi • 3 angel babies 2 on earth

I just opened my app tonight and it made me log in again, only to open with absolutely no past data. I've been using this app for about 4 years and never had an issue. Go figure, I have an appointment on Monday and I need this because I've had concerns about my past cycles and now I don't have that data.

Has this happened to anyone else?!
