After a few days of testing Azure aks, I find myself in a situation where existing aks instances don't clean up when I delete the parent resource group (or with az aks delete) and I am also unable to create new aks instances. Has anyone encountered the same issue?

Curent state:

Creation error in a brand new empty resource group in westus2:
