I have a recurring issue with one of my Sense Apps- about once a month the App suddenly stops saving changes I make, things like new formulas, visualizations, sheets, etc- I add or change something, and then it disappears or isn't there when I reopen the document. The only workaround I've found is Duplicate the App, and then start using the new one. That is a painful solution for a variety of reasons (which I'll post in another question). Does anyone know why this happens, and how to fix it?
