MobileSheets will update user_filters.xml anytime MobileSheets is minimized (or right before it is closed) to ensure the filters are saved if the application is suspended in the background (which Windows can do whenever it decides it wants to, at least with the Microsoft Store version of MobileSheets). This way if a user automatically loads the last used filters, they are properly persisted and available. I'm guessing something is occasionally going wrong with this on your device that is causing the filters to be saved with only the contents of the temporary filter, without all your other saved filters. Figuring out when/how that occurs is going to be quite difficult though. There is code that tries to open the existing filters file to edit it, but if this fails, it will generate a new file with only the temporary filter. I'm guessing this is the code that is triggering. So something is causing MobileSheets to fail to read the existing user_filters.xml file. We need to figure out how and when this occurs.
