Like it, but it just erased all my reminders!

Ive been using Due for several months, and really liked it. It helped me remember daily medications and things that happened less frequently, like giving my dog his monthly preventives. However, it just notified me of a regular occurrence, but when I went into the app to mark it complete, it acted as if I were a brand new user, and walked me through the tutorial. Now it shows that I have no reminders set! This really upsets me, because I actually had between 10-15 recurring reminders programmed in there. Because all of these events happen at uneven intervals, I dont even remember when I had everything set for. Extremely disappointed...
