Steps to reproduce
  1. As a guest user, configure the desktop client to sync all files from the server.
  2. Create a new file or change an existing file (e.g. .txt file)
  3. Force sync
Expected behaviour

I would expect that changes and new files would be uploaded, especially if the desktop client does not report any error.

Actual behaviour

The desktop client just shows the check mark, but new files do not appear on the server and changes are not there either.

Research direction

No source file or test is named. Start by reproducing the guest-user workflow with the desktop client and inspect the guest app's server-side sync and upload handling, using the reported Apache, MySQL, PHP, and Nextcloud versions as context. Done means guest-created and modified files upload successfully and the client reports failures instead of a false check mark.
