Teh,
It appears that your solution configuration is setup correctly as the Save Configuration button is active.
After you have the Customer Insights solution setup in Dynamics 365 you still need to assign Control configuration to fields on the Contact form. In my example I have used existing Address fields but in a production environment you should create new fields for this purpose.

There are 5 different Customer Insights Controls that are available as a part of the Solution, they are Customer Insights Demographic Control, Customer Insights Enrichment Control, Customer Insights Intelligence Control, Customer Insights Measures Control & Customer Insights Timeline Control . You can use any or all of these Controls as needed. To set the Control Configuration on each field open the Field Properties, choose the Controls tab, choose Add Control, scroll and select the correct Control for Customer Insights and then select that you want the Control to use on Web, Phone and Tablet.


So with the Customer Insights Solution for Dynamics 365 installed and configured you can add fields to the Contact form to hold the Customer Insights field controls which will then display Customer Insights data in place of the fields.

I hope this helps, please mark as Verified if it solved your problem.
Thanks,
Scott Roller
