Can you export in Lightroom CC with a watermark / copyright signature?
Can you sync with SmugMug account?
I use MacOs Lightroom Version 5.x and do all the above routinely. Trying CC and learning.
Unfortunately, not at present.
I would assume that you can perform these tasks in LR Classic CC?
Yes to both, although the SmugMug plugin would need to downloaded from Jeffrey Friedl's Blog » Jeffrey’s “Export to SmugMug” Lightroom Plugin
