I have created an Interactive Road Map with animation, sound and hyperlinks. This was working with InDesign 2018 to 2019 when I first published it. However, I needed to update the road map but then once published online using InDesign 2020 all the hyperlinks and sound stopped working. I've tried going back using older versions of InDesign but those features seem to stop functioning. I've even tried re-inserting the URLs for the hyperlinks.

The hyperlinks are on the station names and text boxes.
