Hi AlanKinane, yes you're right, with your help i realized that i was deploying the classic version. I am now trying to deploy the ARM version but I found i am not able select East Asia(i don't think it is just for meta data, even the vnet i am not able to select the East Asia), while i can deploy to East Asia for classic version, please kindly confirm my finding. Thanks.
Weird than, when i tried to create the hostpool(arm version) and vm, i cannot choose East Asia, unless i use the classic version.
