I have had the same problem twice since purchasing the app through the in-app purchase. The app displays a banner at the bottom of the video to purchase the app, as if i hadn’t already purchased it. This also breaks the feature to be able to record multiple audio sources (this feature also requires you to install another app which was not made clear in the description). I now completely do not trust this app to function when i need it to function. Last time I had this problem it took over a week for it to be fixed. I don’t know how long it will take this time. I would go with a different app, but I already spend $28 for this one. Yes $28 if you want the app to be fully functional.
