Default Mac audio player and non-playing on Android

I am working on a file I created ages ago and haven't looked at since created. Each page has its own audio with events. I created my own play and pause buttons.

When testing the course, Apple devices are showing the apple default player and android products are not playing at all.

What am I forgetting?

What version of Lectora are you using? Can you upload a sample course (it could be one page) that shows this behavior, using the "Export as zip" feature?
