My wife and I are both experiencing the same issue in which MobileSheets somehow automatically returns to the library screen.  However, we have both found that the same thing happens occasionally when we are using the browser--not MobileSheets.  Somehow, MobileSheets becomes the active window.  Strangely enough, this happened to both of our computers at the exact same moment yesterday at 10:44 am Eastern time.  We were both using  our browsers when suddenly MobileSheets became active and at the library screen.  We do not have our Chromebooks linked together in MobileSheets, nor linked together in any other manner.

As a troubleshooting method I decided to uninstall and then re-install MobileSheets from the Google Play store and restored the library backup.  However, strangely, three times that day the library screen became active on its own, twice while I was using the browser at the time and once when I was playing a score in MobileSheets. Normally I only experience this anomaly about once a week or so.  However, after the uninstall/re-install, I experienced this three timess yesterday and once  today.
