Plyr.io not working on mobile

Hello, I’ve managed to get the audio player at Plyr.io working but it won’t work on mobile. Can anyone see read-only link and help?

Audio player is in the “web app” page.

Here is a read-only link: https://preview.webflow.com/preview/bickie-new?utm_medium=preview_link&utm_source=designer&utm_content=bickie-new&preview=f9e5af9a6313a89298a9084a1491d03d&pageId=5fa150772ce953e8c75305ef&mode=preview
