Hello, like many people, I got the update that added the individual user folders and changed all the file paths in Dropbox as a result. It looks like shortcut aliases where made to help all the apps that had obsolete paths in Recent Files and stuff, but it has seriously messed Windows File Explorer up in terms of staying fresh.
More importantly, when I select "Make Available Offline" (what used to be "Store Locally") the Dropbox app is usually but not always ignoring my request. In previous versions, the download happened immediately. Now, most of the time (but not always!) I have to kill all Dropbox tasks and services and restart. Then it syncs.
The Taskbar Icon says DropBox is up-to-date before the restart.
