@Daniel Morgenbesser - Welcome to Microsoft Q&A and thanks for reaching out to us. You're correct, currently if you have a new subscription, you can't immediately use the features of cost management, because there could be a delay of 24-48hrs before you can all the features. I have updated this feedback to the product team and got confirmation that they are working on reducing the latency. Hope this helps. and please feel free to reach out if you have any further questions.
