I've been doing this for several years and have never had any problems, then today I needed to add a keyword to a bunch of images, so I selected the images and dragged the keyword over top of them. Like I always have done. Usually they all take the keyword, and I move on.
Today, only the image that I dragged on top of (not all the selected images) took the keyword.
So for instance, I selected 100 photos, dragged the keyword “family” over them, and released. Typically I would see the counter go up by 100. Today the counter only went up by 1.
Is there something “clicked” on that I need to unclick?
Figured it out. “Primary” was checked under the edit menu.
Uncheck and go.
