My apologies -I'm opening a topic that I previously closed.
Awhile ago I was having issues with grayed out thumbnails in Lr Classic using a Mac. I received several well informative and well meaning replies. I finally gave up - went to the missing photos folder (which I now can't find) and deleted all of the missing grayed out thumbnails There were about 1700 of them.
I thought that would solve my problem.
WRONG
I recently opened a collection and found several grayed out thumbnails. I frequently use this collection and have never seen these kind of thumbnails. I called Adobe. They said the cause of these thumbnails was the way I was deleting them from Lr. I have always chosen Delete from Disk. They said that was deleting the original file but leaving the corresponding thumbnail still on Lr. Not sure I believe them. Any thruth to that?
Another weird thing about all of this is that now I am finding the missing files. Some are in trash. As I have been locating these missing files I have discovered that I never put any of these images into that specific collection.
