File not yet available

Hello. On my iPad, I imported a PDF into DTTG2. The database it was imported into uses shallow syncing. I then synced this database with my laptop’s DTPO database. On my laptop, the PDF does not display, but the preview pane says “File Not Yet Available”. And when I click “Download” nothing happens. Any ideas?

What kind of sync location do you use?

This was with WebDAV, which I have installed on a Synology NAS.

Did you uncheck Synchronize contents of indexed items for the WebDAV location?
