Only works when not on a call

Got an issue where the input fields are non-responsive if you are on a phone call, ie if there is an active banner across the top of the phone. The tech support link for this app is also invalid, so seems abandoned. Prior to this I had used the app okay, long as you are not using your phone for calls or navigation etc.
