From the tutorials I found that there are two ways to connect AEM and Target.
1. Using DTM (via adding target as tool)
2. Via cloud configuration in AEM miscadmin and attaching it on the page.
Question-1 What is the difference between the two and when to use which option ?
Question-2
With option 2 I am able to see the results and my activities created in AEM are getting synced to Target.
However, when I create any activity in Target and access my page in AEM, I don't see personalisation on the page. What might be missing ? What are the ways to debug it. I am already using Adobe Debugger Chrome Extn. But not getting clue.
