I have a pile of files synced to mobile, and I can see them just fine on my phone. However, I have a 2nd PC that I use at times; is there a way I can get to the files that were synced from my primary PC?
Yes you can do that. Open your favorite web browser and go to Lightroom.adobe.com. Sign in with your Adobe ID and password, and you will have access to all of your images that have been synchronized. Any adjustments you make to those images using your other computer will be applied to the master images, just like when using Lightroom Mobile.
That was too easy.
