Hello,
we have setup the Multidomain functionality and only use the Stape App in our Shopify Store to supply the datalayer (as mentioned in the docs when using multiple container domains).
That means that the GTM ID and custom domain are left emtpy in the app settings and we supply those in our theme.liquid.
It works wonderfully for all events, apart from anything Checkout/Purchase related.
I assume, the issue is that the custom pixel isn’t setup to work with the Multidomain functionality and therefore it doesn’t properly work.
Has anyone here managed to adapt the shopify customer events pixel to work with multiple tracking domains?
