    Use "https://m.facebook.com/v20.0/dialog/oauth?..." instead of "https://www.facebook.com/v20.0/dialog/oauth?..."

    Same issue. When I create a new app or go to app detail. It's always show "Invalid Email or Phone Number Please enter a valid email address or mobile number." I can't doing anything.

    When trying to access the app i've created, i'm sent to a blank page with Invalid Email or Phone Number Please enter a valid email address or mobile number.
    This is holding up our app development. Please sort this out asap Meta.

    I have a sneaking suspicion that this has something to do with facebook currently being on the news about 600 million user passwords not being encrypted. They're probably doing something with the account credentials to try and fix this problem.
