Hi Bob – Thank you for your feedback. We will consider all of this for a future build. In the meantime I would suggest for your situation that you simply always use the “opt-in” action. It sounds like in your environment you cannot guarantee that computers will be opted-in already, which is fine. I would suggest you simply always run the opt-in action before checking for updates. If a computer is already opted-in, then it will continue to be opted-in. If a computer is not yet opted-in, then you will force it to opt-in when you run that action. This way you can guarantee that you won’t ever encounter “unknown update service”, and it removes the need for you to have a contingent operation for that error.
