Q. Why am I not getting sound or vibration alerts?
A. Make sure they are enabled in the settings screen. In addition for sound alerts, make sure the silence switch is not turned on. Finally, both sound and vibrate only occur when the screen is locked or the app is running in the background. In other cases it is assumed that you are looking at the monal app and dont need the additional notification of a new message.
Q. How do I remove contacts?
