A Microsoft file hosting and synchronization service.
Well folks, I think they fixed it... at least for me.
The other day I noticed a BUNCH of synchronization going on for no apparent reason.
My phone stopped syncing photos for a day couple days.
Today, my laptop and phone OneDrives were just fine. Web version also showed everything it should. (I had new work from each device that all needed to find a way home.)
My desktop failed to sync OneDrive and even stopped showing it in the tool tray. I had to uninstall then reinstall the desktop app.
I had another user in my family share a folder with me. Below is the result of that.
After that finished syncing everything, OneDrive was again showing, files were syncing on all devices, and life was good. The little NE arrow icon is new. I assume that means a shortcut back to its source.
The owner had to "share a shortcut," which I feared would not be a fix, but it behaves just like a regular folder.
Hopefully, you all will see the same soon.
