Hi there
I have configured an ArcGIS Enterprise
Everything is working as expected. -However I have configured the Utility Services (redacted Username/Password)

I have enabled credit budgeting for the user account - and I did some test services. (Geocoding, Buffer etc...)
- This consumed all of their credits - but I found that once the credit limit was gone over. I could still use these services
I got emails from Esri saying that I have gone over the Credit Limit,
Has anyone else come across this?
The ArcGIS Online user is an Administrator if that helps
