Google Analytics And Google Ads Tracking Codes

Hello to everyone,

This is my first post in this forum.

I need some help with my Google Analytics.

I use the Google Analytics add-on and i put there my Google Analytics account number and i checked the box for the Track e-commerce transactions.

In the google analytics page when i go to Convertions -> Ecommerce -> Overview i see that in Marketing Campaigns shows only 0$.

Also in the Shopping Behavior Analysis i see no trackings.

Should i add the Google Ads Remarketing code?

If so how can i add it?

Best regards and thank you very much :D
