Lost data multiple times

I lost my work several times now on the iPad Pro. Most times it’s an app crash related to an Undo process, but several times I have lost data with not app crash. If you need to do critical work, this app is not for you. I have sent in multiple bug reports throughout the course of two full days using the app. I am bit surprised by the number of strange bugs, but I feel confident that the Omni Group will find and squash them, but unfortunately, I need a diagramming app now and will likely revert to the Mac version. (Full disclosure: I’m writing this review immediately after losing my changes and another hour.)
