Let me add that as problematic as 9926 has been on my SP3, it's a horrid hot mess on my Dell Venue 8 Pro. The V8P got downright confused as to what kind of machine it's supposed to be--you'd think it would default to tablet mode, but nope. And, it seemed sort of stuck between the two modes, with some things from each just not working. And it was laggy and non-responsive and just horrible, and OneDrive got confused between the existing OneDrive folder and what it thought it needed to sync. Fortunately, the roll-back functionality worked fine as far as I can tell.
