i have used the application available at https://github.com/OfficeDev/O365-WebApp-MultiTenant and made it as multi-tenant,
using the access token generated in this application i could list down and access the children on one drive for business, https://graph.microsoft.com/v1.0/me/drive/root/children.
This application uses graph end point as https://graph.microsoft.net/ but i noticed that it doesn't work, then i started using https://graph.microsoft.com/
and it started working.
my question which is correct endpoint,https://graph.microsoft.net/ or https://graph.microsoft.com/
