Why is the product displayed without a price in completed purchases in GA4?

Question

Google Analytics

Hello.
I post the following code on the site where GTM is connected:

dataLayer.push({
                        'event': 'purchase',
                        'ecommerce': {
                            'items': [{
                                'item_name': 'Item Name',
                                'price': '500',
                            }]
                        }
                    });

In GA, in the Monetization > Purchases made section, the price of the product is not displayed. And the goods appear with a huge delay. I need to pass only the name and price, without the other parameters they use in the example. Please help me find the reason and tell me why there is such a delay in the list of completed purchases?

Answer 1

with a huge delay

1 second is not a huge delay
