How to add a logo in Windows Azure Active Directory Application?

Hi,

Am developing a windows store 8.1 app

Am doing Azure active directory single sign on authentication and i  implemented this.

I have added a logo in the Configure tab in the LOGO column.

 I have designed the logo as per the logo requirements with 215 x 215 pixels 

• Central image dimensions of 94 x 94 pixels
• Supported file type is .png 
• file size is less than 100KB

Our account is AZURE AD Basic and we have made it as AZURE AD Premium 90 days trial..

Even though i am unable to see the logo in the app.
