Hi Devs, I am in the process of documenting the samples in wiki, and testing if the steps documented run accordingly. I faced the following issue when doing so.
Deployed the Complex-app application in the respective sample. Next the application was successfully undeployed and deleted [1]. There after step by step I removed the artifacts added to the application, but when trying to remove the auto-scaling policy an error message was given mentioning that the auto-scaling policy cannot be removed because the application is using it [2]. Then I went to the UI and checked. It shows that the application is still deployed. When trying to undeploy the application via the UI too, the success message is given saying the application is undeployed successfully but the application does not get undeployed. Do you know why a user might face this issue? Is this regarding to any steps followed when undeploying an application ?
