I am working on a site where enhanced ecommerce is implemented via GTM. However, they are using a transaction tag with a track type of "transaction" which I have read does not work.
However, all transaction data is passing into GA. I assume it is passing in the normal pageview tag but how do I check this? In the preview pane, I still see a "purchase" event passing right after the "pageview."
So my main question is what is a step-by-step way to debug what hit is passing the enhanced ecommerce transaction data? In other implementations I've seen, the normal pageview fires before the ecommerce data is passed and thus does not get sent to GA. Either that isn't the case here, or the transaction tag is somehow capturing the data.
I would also note that enhanced ecommerce specific data is definitely passing (such as product brand).
