Worked before, why do I need a new one? – ZoomNotes Lite Review

To have to download this 'lite' version to my iPad Pro really galled me as the app was working fine before but now suddenly it does not and the Appstore shows two apps. The original still works on my iPhone, go figure. The app also has 'in-app' purchases for everything I had before. Because of the graph paper in it I used for math stuff. Why am I being charged again? Why is it 'lite' when before it was just fine.
