No option to update AI mask when copying from other photos in 12.0.1

[mbanov1]

Hi,

I have a bunch of similar photos with several masks for which I used subject detection. I used to be able to copy the masks from one image to the next and a button would appear "update masks" and the subject would be redetected on the new image. From what I see I cannot do that anymore, I have to recreate the subject detect mask, reuse the brush strokes to select specific parts of the background, and recreate my settings manually for each mask for each image.

I don't see that in my LR 12.0.1.  See the attached screen recording.

Please provide a detailed step-by-step description of what you're doing. Or much better, provide a screen recording of your entire LR window showing the bad behavior.
