I can't see my most recent files in my "recent files" tab

Thanks for such a quick response.  Yes I am familiar with what SmartSync does/meant for (although I think there could be clearer explanation of how to use in conjuction with selective sync as I had quite a few trial and errors on both a MAC and PC until a. I could free up space and b.  could see all my files on my desktop) but now back to the question at hand.

What I am not seeing in "recent files" is basically scans that I do from a scanner that save directly a Dropbox folder.  They always showed in "recent files" in the past until I started to use Smartsync.  Right now I'm typing this on a MAC and I can see "66.3.77 Up to Date" when I hover over the icon. I would have sent you a screen shot of my "recent files (which likewise said "up to date" but since my last posting I went ahead and renamed those files from the desktop so now of course they do how as in recent.  Before I did that the most recent shown was 9 hours ago.  

Thanks so much Lusil for trying to help.

 It's only now showing the expected files since I renamed them. So I just did a test scan (maybe 45  minutes ago)  of a document that sends directly to Dropbox.  And I have the same problem. It’s not showing up in recent although if I go to my files (Finder) it is there.  It used to show up before I upgraded to Smartsync.  I did update before I did the scan.  The screenshot below does show in recent files though!

That is very odd that I’ve been on a beta. Anyway I just updated it as you suggested.

Its even worse on my Windows 10 machine:  Recent Files haven’t updated since yesterday and its been online.

Windows is version 66.3.77

Screen shot also attached.

I try to attach screenshots here but keep getting "An Unexpected Error has occured"

Thanks again and thanks for removing those file links.  

Still same problem with with latest stable build (MAC) and but when I install 65.4.177 it starts and then updates itself to 66.3.77.

One issue seems to be to me that files uploaded directly to dropbox.com do not show up as "recent files" on desktop.

Why however the Windows machine hasn't updated recent files since yesterday is another issue.  That one seems to me to be that changes made on local files on the MAC that have synced with dropbox.com are not then syncing back to the Windows machine. That had all worked just fine before Smartsync.

I just lost my recent files list after the last update.  Really liked that that feature and want it back!

• Are you not seeing the Recents tab in general, or are you not seeing any files included in it? 
• Are you referring to the desktop app, the mobile app, or the website?
• If you’re referring to the desktop app, could you please let me know what it reads when you click on it? Is it still syncing or is it up to date?
• Are you by any chance using Smart Sync on your files?
