Using Lightroom CC/6, all updates installed. In past versions I could rank image while playing impromptu slideshow. Now it acts like you are rating the images just fine, but the info never reaches the image. Has this feature been discontinued, or is it a glitch? I regularly use this ability to rank images as they play full screen, and miss it.
It works fine here on Windows 7.
Impromptu SlideShow - set star ratings by number pad. Stars are on images when I escape back to Grid.
I have the same issue. Only the last rating "sticks" and it sticks on the first file in the set, not the file the rating was assigned to. (I am running Windows 7)
I have Windows 7 but it does not work for me either. When I return to grid, only one file has a rating and it is the last rating assigned to any file (i.e., if the last rating I assign is "4", the first file will have 4 stars even if I had previously given it a different rating.)
