Kevin,
It's only possible to downgrade if you are using the FastSpring version of MobileSheets. You will also have to backup your library, uninstall the app, reinstall the old version and then restore your library, because Microsoft's installer framework will most likely not let you downgrade to a lower version. I do have changes for Windows that are going to be released based on some of the crash logs I've received, but that's very different from the device freezing, and I won't get crash reports when the entire OS freezes. I have heard from other users that had the keyboard attached that unplugging the keyboard made everything work again suddenly, which points to an issue in Windows in that specific scenario. I also don't have any way of reproducing the issue, as, like I described, I ran 10+ hours of testing with no issues. If you want to share your library with me, I can test it on my device, but I don't have a Surface Book to test on (only a Surface Pro 4), so I don't know if the behavior will be different between the devices. If you want to proceed with downgrading, I need to know which version you want to downgrade to.
