I cant open the classic version since installing the CC version I just get some random
catalogue error white writing in black box on the screen.
What I haven't figured out yet is how to apply my watermark to imagines I have edited?
Please tell me it's not something you brainy people in ADOBE left out for forgot to plan for???
This is a user-to-user forum, so you aren't addressing Adobe.
No doubt there was a good reason for Lightroom CC being released so prematurely and lacking many features at least as important as watermarking. These omissions may be rectified, but no-one knows when, or they may reflect Adobe's view of the target market. If you want to watermark photos now, Lightroom "Classic" would be more suitable to you.
Watermarking has just been added for iOS Devices at least.
