iPad syncing suddenly stopped working. It was working fine until yesterday. I sync through WebDAV and that is working fine on other devices in the same network. I tried restarting the app and the iPad and also logging out and in again on Zotero in the iPad but nothing changed.

The only thing I did before noticing the sync issue was annotating a pdf.

I get the error sync failed api response post data not provided when trying to sync.

The error log should comprise the sync errors above, let me know if that worked otherwise I can try to let the logger run for longer.
