I am suddenly getting a 403 Forbidden error when using the /resources version of the Copilot Studio (MCS) licensing endpoint.

Failing Endpoint (Returns 403):

GET https://api.powerplatform.com/licensing/entitlements/MCSMessages/resources?fromDate=2026-11-03&toDate=...&api-version=2024-10-01

Working Endpoints (Returns 200 OK):

Using the exact same token and admin permissions, the base endpoints work completely fine:

GET https://api.powerplatform.com/licensing/entitlements/MCSMessages?api-version=2024-10-01

GET {{ppHost}}/licensing/environments/entitlements/MCSMessages?searchRequest=&api-version=1

Because our token and permissions are valid (proven by the working endpoints above), why is the /resources route suddenly blocking us with a 403 error? Has access to this specific path changed?
