Everytime I receive a Whatsapp message, my HTC 7 Trophy shows a Twitter toast notification. That is, a toast notification is shown with the Twitter logo, but the content of the Whatsapp message, and if I tap the toast, Twitter app is launched. Twitter's tile also shows the number of notifications, while Whatsapp's tile doesn't. However, if I launch Whatsapp, I have new messages there.
Sumarizing, I receive Whatsapp notifications as they would be Twitter notifications. It seems push channels are messed up.
Is anyone else seeing this behavior? It's happening to me for the last 2 days.
