After editing copy in PS and rating it with star in Light room - if saved again in PS the star rating is lost. I have used this method for sorting images and do not recall this happening before as it is the primary way I sort images.
Sure. In LR, I select the image and Edit in PS (Command+E) and work on the image in PS and save, switch back to the LR window I rate the image with 3 stars, the image is still open in PS and I go back and make some further adjustments and save again.
Switching back to LR the image has now lost the star rating. Thanks
