Are JPEGS the only images I can sync with the cloud?
When I create a new collection I do not have the ability to sync to CC. What am I missing?
Click on the pulldown in the identity plate area, and make sure synchronization is not paused. Also, you are using Lightroom CC, is that correct?
If it doesn't show the option to sync you are probably not logged on the creative cloud in Lightroom (follow Jim's directions to find where to log on) or you don't have a creative cloud subscription but the standalone Lightroom.
Thank you and yes I have CC.
