Mobile Safari can only play one media file at a time. As a result, we don't recommend adding multiple audio or video resources to the same slide if your learners will be viewing HTML5 content in mobile Safari on iPads/iPhones. This limitation in mobile Safari can also impact step-by-step screen recordings if they include both audio and video components.
Tip: Simultaneous audio/video resources are supported in the Articulate Mobile Player app.
