What application are you using to view the PDF and test the hyperlinks? (If you use Acrobat, in Preferences > General, Acrobat will try to create hyperlinks from URLs by default.)
How did you export PDF (File > Export > Adobe PDF (Print) or File > Export > Adobe PDF (Interactive)?
If for Print, did you check Hyperlinks on the first panel?
I did File>Export>Adobe PDF Print.
I'm not sure what you mean with the second question. In the Hyperlinks Panel, I checked them all and got a green light on all of them.
Should I try it with File>Export>Adobe PDF Interactive?
Thank you, Steve! This worked!
