The Preview folder in iCloud Drive shows a persistent dashed-line iCloud icon. It has been showing the icon for hours even though all the files have most definitely been downloaded. The folder isn't particularly big either: only 40MB.
A reboot doesn't solve it. Any ideas on how to make it go away?
Best Answer
In the end I solved it by disabling iCloud for Preview, removing the folder, enabling iCloud for Preview again and re-adding the files.
What exactly caused the problem I have no idea, but it's one of those things that really shouldn't happen in the first place.
