I have created a few copyrights, and it has always shown on my photo and when I export. All of a sudden, it is not appearing. I have also gone to edit and watermarks and created a new one, but it still is not showing. I also checked the opacity to make sure it was not too little. Any idea what the problem could be?
Could you please let me know the version of Lightroom installed on your computer?
Also please try to create a new watermark with a new font.
Try opening the exported image in Photoshop, and see if you are able to see the watermark or not.
There is or used to be a bug depending on certain fonts used, I don't know which version it was fixed offhand, but just making a suggestion.
