Facebook permissions window doesn't appear on tablets using JS SDK - facebook

Question

I'm using the login code from Facebooks documentation:
This works fine in desktop browsers but on tablets the whole site tries to redirect to an https://m.facebook.com... URL instead of showing the permissions pop up. The page it redirects to just displays Error. Can pop ups not work in Facebook Javascript SDK?
<div id="fb-root"></div>
<script type="text/javascript">
var likesPage = false;
var addisPageId = 'XXXXXX';
window.fbAsyncInit = function () {
// init the FB JS SDK
FB.init({
appId: 'XXXXXXX', // App ID from the app dashboard
channelUrl: '/channel.html', // Channel file for x-domain comms
status: true, // Check Facebook Login status
xfbml: true // Look for social plugins on the page
});
// Additional initialization code such as adding Event Listeners goes here
};
// Load the SDK asynchronously
(function (d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) { return; }
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/en_gb/all.js";
fjs.parentNode.insertBefore(js, fjs);
} (document, 'script', 'facebook-jssdk'));
function callLogin() {
FB.login(function (response) {
var access_token = FB.getAuthResponse()['accessToken'];
$("#at").val(access_token);
if (response.authResponse) {
FB.api('/me/likes?fields=id', function (response) {
for (var i = 0; i < response.data.length; i++) {
if (response.data[i].id == addisPageId) {
likesPage = true;
break;
}
}
if (likesPage) {
FB.api('/me', function (userInfo) {
document.getElementById("email").value = userInfo.email;
document.getElementById("fbId").value = userInfo.id;
document.getElementById("fbform").submit();
});
} else {
document.getElementById("dontLikePage").style.display = "inline";
}
});
} else {
window.parent.location = "https://www.facebook.com/XXXX";
}
}, { scope: 'user_likes,email,publish_stream' });
}
</script>

Had this issue a while a go. I got around it by using thee facebook login button https://developers.facebook.com/docs/reference/plugins/login/ this works fine on tablets but using the fb.login in javascript just errors because of the issue you described.
