Managed disks not visible in VM Disk Management

I have two VM's; both have this problem. They are running Standard_DS2_V2, which should support 8 data disks.  I created two identical Premium-LRS Managed disks from the Disk blade on the VM.  Upon RDP to the VM, disks do not appear in diskmgmt.msc nor in diskpart.  I have recreated both VM's but the problem persists.
