So I saw some discussion about the notification sound, but I downloaded the latest app, and can't setup that it will make a notification sound, I got the notification, but no sound or vibration, what's the solution?
I really need an answer right now because my client is going to return everything and no further purchase will be made. I found that it is a very unlucky situation, I spent all my time working on the project, and everything seems to be working fine except this notification sound, made the whole thing fall apart, and everything is wasted. It seems to me to be a very simple fix, like everybody can fix it.
