Why are you not syncing your Files from Lightroom and then accessing them on your Lightroom Desktop?
Note that you will still get the DNG image.Log in with the same creative cloud account to both your mobile and desktop apps, and they’ll automatically sync the full res DNGs over.
About the Creative cloud sync, You need to go to Adobe Creative Cloud then choose from your recent uploads.
I found my upload from my iPhone in the Creative Cloud and clicked ‘Download'
to download a DNG file to my Mac, and then I was able to open the file on my iMac
in PS CC, LR or Bridge.
But I have one more, workflow oriented question:
How can I access multiple files in the Creative Cloud directly from LR, PS, or Bridge?
You can only access your Creative Cloud Library from Photoshop. See Creative Cloud Libraries in Photoshop
As I mentioned in last reply,Its best to leverage Creative Sync for Lightroom and sync your images on all your devices.See How to sync Lightroom desktop and the Lightroom mobile app
Thank you! Very helpful.
