Hello.
Thank you for your messages.
Concerning customers comment display, this functionality is currently unavailable. We certainly see how it can be useful. We will consider adding it in one of the future versions of the app.
As for notification sound issue, can you please specify if you have used built-in sound or some custom one?
Finally, you have also mentioned that you want to get a free version. Actually, the app is free, so please, clarify in case you have meant something else.
Regards,
eMagicOne
