Sync problem: not uploading to WebDAV from ipad
I'm using WebDAV server to sync files between win11 and ipad. I uesd to sync correctly between win11 and ipad, but I recently found I could't upload my notes that I made on ipad to WebDAV server. However, the changes I made on zotero on win11 can successfully be uploaded to WebDAV. The network on ipad is working fine and I'm able to download newly changed files from WebDAV to ipad. I thought the upload process on ipad is automatic and I used to upload files from ipad to WebDAV correctly(couple of months ago), so I am confused now.
