Is Facebook App Causing WhatsApp Notification Malfunction?
This happen only recently when I set up Facebook Account (even with the latest version of Facebook released today), it will caused WhatsApp notification not function. No LED! No alert tone! Only when I open WhatsApp then I see the new messages.
So I did this a few times, I will log out of Facebook, remove Facebook App. Delete WhatsApp. Reinstall WhatsApp... notification then will return.
Anyone encounter such issues? I remember reading somewhere someone encounter WhatsApp notification issue.
