Thumbnail images not showing with Big Sur 11.2.3
My company recently upgraded my iMac to one with the Big Sur OS (v11.2.3) and none of the images in my Camera Uploads folder, for example, are showing thumbnail pics, only generic icons for JPGs.
However, if I open up an image and close it, then a thumbnail picture shows. I can't open and close the hundreds of images I have on Dropbox, so is there something quicker I can do to solve that problem?
- Anything in the Dropbox folder is visible and synced to the Dropbox site, if there's a green tick next to it. Online-only files will have a cloud icon, meaning they are already on the Dropbox site, but don't take up space on the machine.
Marking a folder as local only means that the files from the Dropbox site are now also physically taking up space on your computer, since the primary reason for Smart Sync is to save space, so you won't need to move them.
If you need any more details, feel free to message back!
Hallo, Jay --
It seems to be only the Camera Uploads folder which isn't showing thumbnails and, since I wrote in, some random ones have shown up. But many are still just generic icons. I don't think I have Smart Sync on. Files are online only until I copy them onto an external HD.
Thanks!

If files are online-only, then you do have Smart Sync enabled.
If the files are local, do the thumbnails appear?

Hey djrocks66, sorry to hear you're having issues with this.
Does this happen with online only files or even files you've set to be available offline too?
What is the desktop app's exact version and status as shown in your menu bar at the moment?
Also, have you tried refreshing your Finder or rebooting your computer?
- I am not home to check Dropbox version but I’m pretty sure it’s the latest. I keep all my files offline and never had this thumbnail problem before until I upgraded to Big Sur. Like I said… my Windows 11 computer shows the preview thumbnails. I have restarted my Mac and still no preview thumbnails.
