It used to be that buttons were able to be interactive when exporting an InDesign design to PDF, which was especially essential when prompting readers to turn to the "next" or "previous" page. Why does it default to making them a) invisible and b) not interactive? The functionality is still there for hyperlinks, but only after you select them to be, which is also a contradictory default. If I add a hyperlink, clearly I want someone to click on it. Seems like we went back a step in functionality after the latest upgrade.
