Embedded JS fusebox mp3 player does not display

Ever since the update to version 2.0.22, javascript mp3 player embeds in previously set-up accordions stopped displaying. Since they were THE central component of a new product rollout that was already in progress, we had to roll back to version 2.0.21 of Easy Accordion to make them visible again. However, this is problematic, since the plugin author has indicated that 2.0.22 includes security fixes. We had hoped this would be fixed in the next version, but the problem persists in version 2.0.23.

The embeds are created on the fusebox website, and the embed code format is as follows:

<script async data-type="track" data-hash="[10-character alphanumeric video identifier]" data-track="6" src="https://app.fusebox.fm/embed/player.js"></script>

Since I don’t want to advertise that the site is running an insecure version of the plugin, I am not posting any links here. Also, the pages are password-protected. However, if the plugin author would like to provide an email address, I’d be happy to provide a link and page password.
