I no longer have sound in the app! The microphone function doesn't work! The app has closed or crashed! I have an issue buying the full version. I bought a full version on my iPhone/iPad/Mac. Is there any way to restore the full version on another Apple device without repurchasing?

Do you have a problem buying our apps in the French overseas departments and territories? I bought a full version on my Android device. Is there any way that the app can be added to another Android device without repurchasing?
