I have a screen record of the entire process described here if you wish me to post it.
RAW image, duplicate and edit in Photo to reduce saturation to B/W.
AP - B/W image - import from Photo, loads the unedited RAW image into the Develop Persona
AP - B/W image - drag and drop from Photo, loads the Photo edited image into the Photo Persona
This process has not been fixed from the last betas.
Is this the way that this process should be working?
