Just happened to me and can’t believe it. Hour long session of taking important notes gone. Curious what other folks are switching to. This is beyond unacceptable. Can it really be so hard to save state on the app for something this important? Can I in good faith use this app ever again given the possibility of not remembering to press save and losing everything? I didn’t even change apps. It just went to lockscreen during a break and that was enough to trash the notes.
