angular-devise Auth not working until page refresh

[Sharespot]

I'm using angular-devise and I have the following service that checks whether the user is logged or not

 isAuthenticated: function ($state, Auth){

 Auth.currentUser().then(function (){
 console.log("user is logged");
 }, function(error){
 $state.go('home',{});
 console.log("user is not logged");
 })

The problem is when I log the user on the server side it keeps returning that he's not logged in until I refresh the page. Then, after the refersh, it says that the user is logged as expected.

What am I missing here? Thank you!
