Audio not playing on Mac, Safari version 12.0.3

I've had similar issues reported with Safari not playing audio for my students, for courses published with the March 5 update to Storyline 3.  My courses are all auto-play, so if I'm reading all the information correctly, all of the auto-play content with audio will not play correctly on Safari?

The security update sounds like it is meant to address an issue where content (audio) plays unsolicited in a browser.  However, with Storyline courses in use, the user is clicking to open the presentation, so there is a click.  However what it sounds like Storyline reps are saying is that each slide in the presentation is treated as a new interaction, therefore if the slide auto advances, the browser will prevent audio from playing on each of the slides.

I feel like this is a poor user experience to have to click advance on every slide.  Many of our slides are very short, 5-10 seconds, while others may last several minutes.  On the back-end, it's really a decision of how to organize the presentation so that the course designer can keep everything straight.  We don't want the back-end to be a limitation on the front-end.  We want the user experience to be as seamless as possible, and as intuitive as possible.  Adding required "click-to-advance" functionality, at irregular intervals (10 seconds, or several minutes) that don't actually require any feedback or real interaction from the student is a negative for the student experience. We feel a better experience is to reserve student interactions for those times in the course when they actually need to provide feedback, such as completing an activity or answering a quiz.

So am I understanding correctly that there is currently no solution for Safari for auto-play content with audio?  The "solution" is either to disable auto-play, or to use a browser other than Safari?
