MS Teams Mobile App issue - Receives non Admin in Mobile and Admin in Desktops App (MS Teams SDK)

Hello,

I am facing issue in Mobile App. I am ussing MS Team Javascript SDK. I am using property called "context.userTeamRole".  If I use this property in Windows desktop or Web version, I receives User is Team admin or not. but while accessing same page in mobile, I always receives user as non Team admin. 

In conclusion :  MS Team JavaScript SDK treat all user as non adming in case of mobile and defined user role in case of Desktop or web application.

microsoftTeams.getContext(function(context){ 
var teamAdmin = context.userTeamRole;
 });
