This is an on-prem SharePoint 2016 server. Attempting to upload a file results in a status of “uploading 1 item” that never completes. This happens when using the upload button as well as dragging-dropping files into the library. After switching to classic mode via the “return to classic OneDrive” link at the bottom left, the upload works fine.
Uploading files to other libraries in SharePoint works fine, this issue is only impacting the OneDrive libraries, as far as I can tell.
Any suggestions of what to check for why the file upload doesn’t work for OneDrive while in modern view?
