Ok, about the red dot thing. I've been facing this bug too, but what I've discovered is that this happen every time I send a message to a certain Iphone user, I don't know if it can be a problem on how the Iphone version of whatsapp sends the confirmation of received that mess up with our version or what, but to get rido of them I have to restart the app several times (as suggested in some previous posts). The other thing that i can say is that this user has in her status as Occupied. I hope this information helps the developers to squash this bug. Regards, and thanks to them to bringing us back to life in so little time.
