@Erik Goes (0991223) Thank you for reaching out to us!
I understand that you are finding it difficult to use your Azure subscription which appears as not associate with Azure default directory. You need to first set the default directory by going into Azure portal settings tab and then associate your subscription to that directory. For reference - https://learn.microsoft.com/en-us/azure/active-directory/fundamentals/active-directory-how-subscriptions-associated-directory
Hope this helps!
