PDF preview using Windows EXplorer
This is for my work account. We use smart sync at work.
Using Windows Explorer if I open a folder I have never been to and there are PDFs present. I will then click on said PDF. A preview pops up...
So not only did this solution not work. It made things worse for a day.
It no longer shows the icons for what is synced and what is not synced which was very useful. I have been using smart sync and liked those icons. No previews for any file. It seems to have reverted back after about 24 hours.
I can confirm I've seen the same issue on two separate machines the past week.
All files are online-only and when I click one, it previews normally.
It downloads the file and changes the file to a green tick (locally stored, selective sync).
After the file has been stored locally with the green tick, it will no longer be previewable.
The preview pane is blank.
If I copy-paste it to a different folder however (documents, downloads, etc), it previews fine.
The only workaround I've found is to right-click the file/folder, select Smart Sync and change it back to an online-only file.
This however only works once as once you click it again it will download itself again and store it locally, cycling the problem.
Is there anything else we can try here?

I use Nitro PDF Reader as my default PDF viewer/editor. It took quite a bit of communication with Nitro's support team to fix this issue and it's still not perfect, but pdf previews do work for me most of the time now. If I find it's suddenly not working, I simply close and re-open the Windows Explorer window. It would still be great if this issue could be solved so that previews work reliably, but I'm not sure if it's a Dropbox software bug or a pdf viewer software issue.
FWIW, I'm using Nitro Pro 13.42.3.855.
