Hi, Greetings for the day!
When our client is trying to delete multiple files (in single operation) from SharePoint Online site, its not working. If we delete single file, its working fine. Multi file deletion is not working from client network. It throws error "X items weren’t deleted from Documents". If we access SharePoint Online site from public internet, multi file deletion is working fine in Modern site experience.
In Classic site experience mode, we don’t see this issue. We were able to delete multiple files in single operation. If anyone has experienced this issue in the past, please let us know details on the resolution.
Console & UI error message:
