Sound not working / no audio on iOS app (iPhone, iPad)

Every user that has reported this issue has had the master hardware volume switch on the side of the iPhone/iPad set to “off”. Can you double check to make sure that this is on when using the Hooktheory app (see image below) ?

We realize many video and music apps (iTunes, YouTube, Netflix, etc.) don’t mute their output based on the status of that switch. We are working on a fix so the audio from our app plays even when the master hardware with is set to off.
