Hi @Anonymous ,
There could be several reasons why you are unable to drag and drop files within SharePoint Online. Here are a few things you can try:
- Check if you have the necessary permissions to drag and drop files in the library.
- Make sure you are using a supported browser. SharePoint Online works best with Microsoft Edge, Internet Explorer 11, or the latest versions of Chrome, Firefox, or Safari.
- Clear your browser cache and cookies, and then try again.
- Try using a different device or computer to see if the issue persists.
