Re: Acrobat Pro DC Trying to add save button and save fillable PDF

Ideally, you add a button to the PDF, select the MouseUp trigger on the properties dialog for the button, And then select "Execute a menu item" for the action. Then select the "Edit->Save" menu item.

Unfortunately this doesn't work because the Save menu item is blacklisted for form operations.

Here's an article on how it's done.
