.then not running on android device standard internet app

I am trying to use sweetalert to open a alert message to allow for the user to reset there password via email. It is able to open the first message asking for the menu however the .then function doesnt run. This is the current code below for the javascript:

function forgotPassword() {
    swal({
        title: 'Forgot Password?',
        input: 'email',
        text: 'Please input your password',
        width: '60%'
    }).then(function (email) {
        swal({
            type: 'info',
            html: 'A reset email will be sent to if the account exists: ' + email
        })
    })

}

I am currently using a Galaxy S6 using android 6.0.1 with the internet browser that comes installed and not chrome. Once you use the chrome app it works fine. Ive tested it on my other devices (Windows 10 phone and iPhone) and it works fine.

It is expected to run just like you have in your documentation because I copied and pasted the code pretty much but some text changes and put it in a function.
