Is anyone else getting the error "This site is read-only. You can't make any changes to files or folders on this site." I receive this error through the One Drive app when syncing down a SharePoint document library with columns that are required. I also did remove those columns to have required values (still kept them on the DL - I understand they don't display in the file explorer) and attempted to re-sync and synced the library and did so without issue. Another facet of this error - the Document Library on SharePoint Online with columns as required; if I were to drag and drop from the file explorer, the Document Library will know if there are required fields and prompt me by revealing the right side pane and fill that information in before adding it to the library. I have attached that screenshot as well.
