This may be something with iOS 7, but I'm seeing our apps ask for access to the microphone at launch. What triggers this? We aren't using the microphone in the app. At least not that we are aware of.
Edit: We have 12 apps in the App store. All of them launch with a warning requesting microphone access in iOS 7. You can choose don't allow because the apps don't use the microphone, but we need to figure out how to remove this. Our apps range from air 3.5 to 3.7 I believe. It's affecting all them in the same way. They all show up under the privacy tab in iOS 7 with a toggle.
