========================================
Vibrate does not work for Whatsapp notifications - New msgs for Direct or groups chats
I have checked all related settings and it seems to be correct, This is the only app having the issue.
I have tried clearing cache, reboot, re-install etc - No luck in fixing it.
I tested other IM apps like Telegram and it worked, New msgs on instagram also works
