Macbook Bridge 2021 smart collections vanished
A few weeks ago I helped a friend sort out his whole collection of photos in Bridge and set up smart collections for all his keywords. When he opened bridge this morning all the smart collections have vanished.
He has updated to the latest version of Bridge and is on a Mac Book with the newest operating system.
I don't want to have to go through the whole process again and, even if I do, I need to find out what went wrong to avoid it happening again.
Thanks in advance (hopefully)
