2. Go to any WP and upload a file to the Sharepoint storage

3. Begin of the insertion~~LeaveEnd of the insertion Begin of the deletion LeaveEnd of the deletion the browser page with the WP open for some time (i left it open Begin of the insertionovernight)~~ (refreshing immediately should also have worked to reproduce)End of the insertion Begin of the deletion overnight)End of the deletion

4. Go back to the page and refresh


### What is the buggy behaviour?

3. Files are accessible
