Hi,
I’m having some trouble with interstitial ads where they seem to kill the system audio player on iOS.
For example; If I’m listening to a podcast, and open my app (and the interstitial (mraid) gets preloaded), the podcast stops, and the system audio player resets.
When debugging using a simulator, and breaking on any exception, I can see that something gets thrown here:

Because of this, the app isn’t really usable, as it will force the user to go back to the music/podcast app to resume playing whatever they are listening too.
Any ideas?
