Damien Murphy This sounds like a good scenario to occur as the expectation is the app-id needs to be unique. It would be good to have the status of the CR updated to reflect this is the cause of the failure.

It would good to also check out if it works correctly in creating a second app when the app-id is changed.

Also, apologies, it is my fault for not updating the description of this JIRA. What I was hoping to get from this JIRA was what would happen if you done the following steps below. To see what would occur to an existing CR residing in what used to be a valid namespace in APP_NAMESPACES but isn't any longer.
1. Update APP_NAMESPACES Env Var to: mobile-security-service-appz
2. Action: make create-app
3. Update APP_NAMESPACES Env Var to: mobile-security-service-appz-new
4. Action: edit app-name in CR. Can be done through Resources > Other Resources. Dropdown to app CR type and edit yaml on the CR.
4. Action: make delete-app
