I use LR (currently the release 6) by several years but I never managed to export the description from LR to FB.
The title is exported properly but the description is lost.
How can I fix this?
I think this is a FB limitation. Only displaying the title and copyright fields.
You could create virtual copies and then copy and paste the caption metadata into the title filed, Then use the VC in the publish service, at the same time protecting the metadata in your original.
Thank you, 99jon!
