I have probably figured it out. Go to your shopify and check the bell in upper right corner. I had message there saying shopify needs proff of my identity (send them photo of driving licence or goverment ID card)

Hello,It  seems I have the same problem. First picture is how the page is supposed to look according to tutorial on your YT chanel. The second one is mine, there is a box saying credit card, but there is nowhere to fill my card details. I use shopify...
