Camera Upload thumbnail not showing on mac

I have the same issue, but with the Dropbox iOS app (newest iOS update) - newly synced photos and videos doesn't show thumbnails in the "photos" tab in the app (ie. it's like they aren't synced, they don't show up there at all), they're synced though (they show up in the "camera uploads" folder). Any idea what's happening? 

This problem is happening on both my macOS computers.  Latest software of everything.  Nothing I can do makes it display thumbnails anymore.  Super frustrating!  And I am a paying Dropbox subscriber.

I am afraid this is a dropbox-mac issue. I just started using Camera Uploads for the first time for my new iPhone. All images were completely uploaded to Dropbox and then downloaded to both my Window 10 system and my Macbook, both with default setting to make all files available offline in the DB settings for each device. The images were fully downloaded to Windows but on my Macbook they show as zero bytes files without a preview. When I click on a file, it appears to download it and I can view it, a little later the size is updated in Finder, and then (maybe) another while later a thumbnail is generated. This means that Dropbox is not correctly downloading/syncing the files to my Macbook, while it does it fine on Windows. The column "Date last opened" in finder does not show any info, but I can select 20 files and open them in the Preview app. They then are downloaded and for all those selected files, the "Date last opened" column shows the same time stamp of that moment. Obviously, Dropbox is not correctly downloading these files to my macbook, or treats them as offline files despite my settings. 

Could you please have a look what might be wrong here? 

Hello Jay,

I am having the same issue as reported many times by others, and I explained the details in another thread (after previewing the zero bytes files in the Preview app on Mac, the files are downloaded). This is not a Smartsync issue and this is not a slow syncing issue. The uploaded files were completely and fully downloaded and visible to my Windows system in a matter of minutes, and my Macbook shows zero byte files. There is something wrong with Dropbox syncing to macbooks, obviously. We all are reporting about Macbooks here, and Dropbox is the common denominator. It's not our macbooks and not our sync settings. I have used Dropsync app for years to selectively upload my photos from Android to Dropbox manually after editing these images on my device. This is the first time I am using Camera Uploads feature and this is the first time I am seeing this zero bytes issue. I have as default setting to make all files available offline on both my Windows and Macbook. All works as expected on Windows, but not on my Mac. Please address this correctly on your end. 

I have made a screen recording of what is happening. Notice how first the column "Date last opened" is populated the moment Preview app starts opening these files, and then the file size column is populated with the file sizes after they have been downloaded.

Hey be-each, thanks for your nudge on this.

Can you let us know a bit more about your setup? What's your macOS version?

Also, if you hover over the Dropbox icon in your menu bar, what's the Dropbox version and sync status of the app?

And lastly, if you go to the "sync" tab in your preferences, what's the location of your Dropbox folder?

I'm still having the issue as well - 

211.4.6008 Dropbox Version

14.6.1 MacOS

Folder Location - users/MYNAME/Library/CloudStorage/Dropbox

Hi Hannah

I have macOS version 13.7.1 (22H221)

Dropbox is 211.4.6008 (up to date)

Dropbox is located at /Users/myusername/Dropbox

Looking forward to your reply!

Hi from me as well, be-each! Can you send me a screenshot of the default sync settings you have under your Sync tab here, so that I can take a look? I’m unable to access the screen recording you sent us above, unfortunately.
