I had a Pod which I was using for getting up to speed with HCoA and it was stuck at manifest 1976.2. I requested an upgrade but was told there is an Azure issue that needs to be fixed. Several months later I was still unable to get it upgraded so I ended up deleting it and starting again. The new Pod came out as manifest 2298.0. The HCoA portal still says "Horizon Cloud Multi-Smartnode
Version: 2.2" I'm told that is also a bug!
I have a Customer Pod that is on the same manifest 1976.2 and they have support with VMware so we'll see if I get any better info when I raise the SR.
