I'm working with Lightroom and Flickr. I haven't had any issues exporting with a watermark when I export the initial collection but when I want to add photos to the collection and publish them my photos are published successfully but the watermarks don't show up. The settings show the watermark box checked. I'm working on a PC.
Thank you in advance.
Hmm, that doesn't happen to me in my quick test, but there have been lots of reports about problems with watermarks in LR 6. You might post a problem report in the official Adobe feedback forum: Recently active topics in Photoshop Family about Photoshop Lightroom. This forum is a user-to-user forum in which Adobe rarely participates, but they say they read every post in the official feedback forum.
