Hello @Adam Eslinger ,
"Unusual activity detected with your subscription" — is not caused by your code. Instead, it indicates that Microsoft has flagged the customer's subscription due to suspicious or potentially abusive activity.
The error is tied to subscription-level restrictions, not a bug or misconfiguration in your deployment template.
Ask the customer to check Azure Service Health: They should visit aka.ms/azureservicehealth-securityadvisories to see if there are any notices or restrictions on their subscription.
Have them contact Microsoft support via aka.ms/SubMngmt to resolve the issue.
Please let me know if you face any challenge here, I can help you to resolve this issue further
