I couldn't see my hub & things status on https://graph.api.smartthings.com/

Actually, i’ve used https://graph.api.smartthings.com
But, a few weeks ago, i can’t use all of features.
for ex: i just can see these message when i access to ‘My Locations’ menu

How can i get the authorization?

I think you need to contact support@smartthings.com I doubt anyone in the community can really help with this issue.
