The page on scaling an API Management service (https://docs.microsoft.com/en-us/azure/api-management/upgrade-and-scale) indicates there should be a "pricing tier" blade under "deployment + infrastructure" (along with several others), but my service only has "external cache" and "custom domains". Clicking the "pricing tier" link from the overview page does nothing. Where do I change the pricing tier?
Note: this is an ARM-template-created consumption-tier service created about 2 weeks ago.
