If an EA is critical due to "Access to usage report is denied", this is likely being caused by a 404 "Not Found" response from Microsoft when we attempted to collect the current months EA usage:

There are a few common reasons why we might get a 404 response code:
- No active subscriptions in the EA - check in EA Azure portal that the EA has active subscriptions.
- No usage in the EA subscriptions - check in EA Azure portal that the EA has subscriptions with usage
- EA transferred to another EA - check which EA you are setting up in Azure, and which one actively has usage in your Azure portal
- Data integrity issues on the Microsoft end - this is the least likely root cause, where Microsoft temporarily returns 404s when the platform requests usage until they resolve data validation checks on their end. This typically resolves within a day. Only consider this case if you’ve validated the first three reasons are not the root cause.
