I just updated to the most recent AdColony framework (2.5.3.1), and have had issues with running on the simulator. Every time I try to display an ad, the app crashes. Looking at the trace, it appears to be something related to Audio for the ad. I've attached a picture below.
In addition, the onAdColonyAdAttemptFinished delegate method is never called, only onAdColonyAdFinishedWithInfo.
Are these known issues?
