Review 360 not playing audio

I'm also experiencing this problem. The slides in my Storyline 360 project are set to auto-advance without any interaction and have text-to-speech voiceover. When I review the project in Storyline, the slides function as expected. When I publish the project to Review 360, however, I cannot hear the voiceover on the 2nd slide.

To hear the voiceover, I have to click the <PREV button on the player to return to the title slide (which has no audio) and then click the NEXT> button to return to the 2nd slide.

This problem occurs only on the 2nd slide and only when I'm auto-advanced to the slide after launching the review. Subsequent slides have voiceover, but don't have that problem.

It occurs in both Chrome and MS Edge. I've attached the Storyline file.
