Whenever I get a message in WhatsApp on my mobile, I recive 2 notifications on the second device (notebook). The first one is a summary of all unread messages, the same that appears on my mobile, so that's what I expected. But there is also a second one sent separatly for the last message, which isn't really necessary. (Screenshot added) Can somebody explain how I can avoid to get this second notification? Btw, this only happens for WhatsApp notifications, and for no other application.
