Got a similar problem here too. I have the app on my iPhone and that managed to connect via Facebook as soon as it was installed however when i try to link my Waze web account to Facebook it just does nothing. This means that when I use Waze via the web it does not pick up all of the points or journeys that are showing on my phone.
Hello, I have now registered with Waze. When I try to use my mobile phone to connect with Facebook Waze then I get an HTTP 404 error message I have a HTC Desire mobile phone. If I'm on the website login at Waze and there with Facebook trying to link me nothing happens. The first time came to the login screen of Facebook and still no connection to Facebook.
