I'm not quite sure if this problem exists with someone else, I couldn't find it anywhere on the Internet.
There is a particular contact whose notifications I never receive. By notifications, I mean the ones that come on the top. I need to specifically open Whatsapp to check his messages.
I'm able to see notification of other contacts, and he is able to see mines. Also he has checked by sending message to some other contact, and they do get a notification.
I don't know if there is a secret option to turn off notification for a particular contact, is there any way to fix it? I've already tried reinstalling Whatsapp.
