Yes.
My largest notebook is about 8K and I have yet been able to fully download it on any version of v10. I leave it plugged in with the screen on and what happens, every time, is that it will get about 50% through and then the app will close. Restarts will move it a little more and then the app closes. After a couple of restarts the app becomes unstable and I have to delete it and reinstall to even use it. My next largest notebook is around 700 notes and that, and other smaller notebooks will download, but the large one never does. I now, unfortunately, keep the large notebook deselected from offline download. Every few new versions I will try again ... ever hopeful.
