I think this is a MobileSheets problem and not an operating system problem, and there is good evidence to support it.  I use my Chromebook a lot for things other than MobileSheets, and I have never had an app close or reset. Mobilesheets is the only one that does. I have done a web search and can't find a similar problem on another Chromebook app.  Like the poster above, I have also had it happen on my Android phone. Finally, it happens when there are no obvious operating system changes such as a network change--not to mention that other apps tolerate network changes and other changes gracefully.

This bug has disastrous consequences, and it has happened to me twice in solo concerts. PLEASE take another look or figure out some way to add debugging info. And, again, I repeat my request for a button to restore one's page in a playlist which would at least minimize the disruption.
