there should be popup alert msg in notification bar, not in app notification. it must be notification alike other apps eg what's app msg, mail, fb notification,message. today one person stolen my milk container while we were sleeping. if message notification would came on my cell we would have caught him instantly. improve this app istantly. worst app and camera, we can't even see his face. To manage notification one has to open app and then see notification. How insane develor is. Non sense!
