For at least 1 year we were using /v1/customers/{{CUSTOMER_TENANT_ID}}/applicationconsents endpoint to auto-grant consent for partner app to the customer tenant. However starting from today the endpoint returns 403 without any further clarification.
Did anything change on the endpoint itself? Is there a workaround?
Note: There is a valid active GDAP relationship between partner and customer, with Global Administrator role assigned.
The issue was resolved yesterday. We have created support ticket through Partner Center portal, and confirmed that it was an issue with latest build, and later it was resolved.
