I have a document library that contains about 8000 files in various folders in SharePoint Online.
Up until today, I haven’t had any issues, but starting today, I can no longer drag & drop files into any of the folders. When I drag a file over the library, it says the normal “Drag the items to any location” but dropping them does nothing.
I can use “New -> Item” and upload files individually however.
Another user who needs to get the files now goes into the library and does not have a Download button on the bar at the top of the library. She only has “Delete Item” and “Move To”. That’s it.
I created a new test document library in the same site, and I can drag & drop to it without a problem. Did MS roll out some restriction today?
