Click on the "Open in Django" button on the card and verify that you are linked to the subsidy page for that subsidy by cross referencing the uuid of the network request url with the uuid of the django page.

You can do so by cross referecing the uuid of the network request url with the uuid of the django page.

Is there a need for a new LICENSE_MANAGER_DJANGO_URL variable if the value is the same as the existing LICENSE_MANAGER_URL?

[katrinan029]

yes, the LICENSE_MANAGER_URL variable is use for fetching subscriptions data and the LICENSE_MANAGER_DJANGO_URL is used as the django admin url. we ran into an issue with fetching the data when we used the same url. the fetching one should be license-manager.edx.org and the admin django screen is license-manager-internal.edx.org.
