Audio events not playing during runtime on iPad

We have a simple file running in React with a single boolean that plays an animation with associated audio events when toggled "on" and another set when toggled "off". Everything runs as expected when on desktop, but for some reason, the audio doesn't play when running on iPad. At first we thought it might be another quirk of the nested artboards, since initially the audio events were situated in the child artboards rather than the parent. However, putting everything in the main artboard still didn't solve it.

Has anyone else encountered this? Is it a known issue?
