I was trying to setup the social insights to my current trial of Dynamics 365 Online. All of my users have the Dynamics 365 Plan 1 Enterprise Edition license which includes a Microsoft Social Engagement Enterprise. However, the admin for Microsoft Social Engagement does not show but a tile shows up in the apps. The application however does not open and says the application is not available. At the CRM admin settings, the social engagement does not also show any instance to connect into. How do I setup a Social Engagement Trial for my Dynamics 365 Trial? Do I need to buy license to subscribe into Social Engagement application?
