Last night I updated to 1809, and it all went smoothly, but then I find that all my files in Documents are DELETED. Gone. Poof. This included many crucial documents and financial info. Yes, I have a backup (I think - using Windows Backup to a NAS). But this is pretty bad. Did no one in the first two rings run into this yet?
I understand (from the news) that this happens to all files in Documents that aren't synced to OneDrive. Further, the Documents folder is really an agglomeration of "Documents" from several different paths - not sure how that works, and it may or may not relate.
