I've been evaluating VM Applications and have run into a bit of a wall. I've followed the instructions in the documentation and it has worked if and only if, the VM is in the same region as the App Definition. When I created the App Definition I specified East US and targeted Australia East as a replica. I can successfully deploy the application to a VM in East US, but when I try one in Australia East, I can see the application version, but I can't select it (no checkbox).
One thing I noticed is that the replication status says "unknown" I left this overnight and it remained the same.
