Using my MSDN Professional Account, I get a certain monthly credit on Azure. I am able to allocate normal VMs, but when I try to use spot discounts, I get the error below. I have tried different regions (US East, US West, etc.), different VM types (D4_v4, D4as_v5, etc.), and there doesn't seem to be any restrictions on my "usage and quotas" page. Does anyone have any suggestions? If I uncheck "spot discount", the VM validation passes.
