Button in PDF form does not work on MacOS Mojave
I'm trying to fill out this form using the latest version of Acrobat Reader on MacOS Mojave:
https://www.uspto.gov/sites/default/files/patents/process/file/efs/guidance/updated_IDS.pdf
The buttons in the PDF don't work. The "Add" button is supposed to add a row to the table, but it just flashes yellow and does nothing.
Why doesn't this work?
