I have observed that when a only receive folder has very long paths, some of them get marked as “Locally Changed Items”, and so they remain no matter how many times you push “Revert local changes” button.
The files are right, all the data is synced without problem, even in those long paths.
As it could be due to the local filesystem not being able to show some of their properties, I configured the paths of the folders with the long path prefix: \\?\ + path in order to tell windows there are long paths. No changes. Still Local additions but well synced.
Environment: Windows for only send device and windows for only receive
