How do you check that the container is not loading?
Also, are you using the Stape plugin? Is it active in your embedded apps? (online store - theme - customise)
I ran into another issue. I don’t receive GA4 client events in the checkout. I do on other website pages and on the purchase page (no checkout extensibility yet). The weird thing is that data client events are coming through. Do you have any idea what can be the reason for this?
Do you mean in preview? If so - that’s expected behaviour and pretty much has to do with checkout extensibility specifics. Data Tag just overcomes those
