Azure Mobile Service Single Sign On

I have a problem using single sign on with azure mobile services.
I'm using the .net backend.

Whenever i call

MobileServiceClient.LoginAsync(provider, true);

so with the single sign on option enabled.
i can fill in my credentials but then the authentication screen stays white.
 
i get the same result whether I'm using Microsoft or Google accounts

When i don't pass the Boolean option, everything works fine but then i have to enter my credentials every single time


What i did:

 1. I followed the tutorial on the msdn documentation :Documentation
 2. I associated my app with a store app
 3. I filled in the Google secrets in the identity tab of the mobile service
 4. Did the same for the Microsoft account
 5. Added my store app secrets to the push tab.

I can't figure out what I'm doing wrong.
For the Microsoft account I can use the live sdk as a workaround. But I would really like to use the same experience for Google accounts.
