Unable to Retain URI Action in Button Field via Java SDK or Acrobat on macOS

Hello Community, 

I am so incredibly frustrated. After several months of trying to get my PDF to have a clickable, hyperlinked PIN in the footer of my document and at the end of my document, I decided to use Adobe API services. So currently I am using the following: 

Adobe PDF Services in a hybrid relationship with Java on my online portal

I've created a PDF template with button fields (PIN1, PIN2) - I had previously tried text fields and this didn't work! 

I want to do a Mouse Up → Open Web Link action but this does not show up on my Mac Mini! 

Acrobat on macOS won’t save my document consistently

My backend fills the field labels just fine, but the hyperlink must be baked in or inserted via Java, however this is not working out at all. 

Does someone in this vibrant community have any ideas? I am beyond frustrated with this now. 

Thank you all. 

Liz.
