File not yet available and won't download

I’ve got a whole bunch of files that I scanned recently and are in my Inbox, but clicking on them reveals a thumbnail and “File not yet available”. Clicking on Download button shows a busy spinner for a few seconds, then nothing. How do I fix this?

I use DEVONthink Pro Office on two Macs and the iOS versions of the app, syncing via Dropbox.

Are you indexing files?
If so, have you unchecked Synchronize contents of indexed items for the Sync location?

Clicking it where…? In DEVONthink To Go 2?

Sorry, I am a real beginner to DEVONthink despite having had it for a while, so I don’t know if I’m indexing files and what the consequences of doing so would be.

And I’m trying to click the Download button in the Mac version.

The originals were scanned into the iMac and they are not downloadable on the same iMac.
