You noticed a big performance drop in sales, Acquisition costs and traffic quality. We know that if Facebook doesn't have the right data, we can't do retargeting or remarketing, or generate loyal customers. For this we need to setup Facebook Pixel and Conversion API properly.

Because your Facebook Pixel and Conversion API data is not coming to the Event Manager correctly. As a result, you will lose a lot of money in your business if you remarketing retargeting to them.
