Is your vCenter added? If not using Composer, are you licensed for Instant Clones?
Thanks for the reply. Yes fully licensed and using composer. I actually had a reply from the VMWare support team who are saying that it is because we are running Horizon Version 7.5 and the HTML5 console has limited functionality in this version. They are saying we need to upgrade to a later version at which point the missing functionality will be available.
