To get the admin consent prompt fixed, global admin in your tenant has to access the application and consent on behalf of entire organization.
If you are trying this in work on application which is configured in "Microsoft.onmicrosoft.com" tenant then you will need to submit your request in http://aka.ms/itweb/filloutaform This will be handled by internal Microsoft team (MSIT).
