Hi RonakB,Please find the response below:Question 1:Leveraging a tag
manager allows you to deploy multiple tools through it. Cloud config is
a legacy approach and is not recommended.Question 2:Please elaborate, I
understand from the question that the activity is created using Adobe
Target interface (VEC). Are you testing for changes on the public page
or are you testing this within AEM? Within AEM you will not see any
change on the page.Thanks,Rohit
