How to Complete Step 4 on Etsy to Open My Store

I am trying to open a store on Etsy, but I am stuck at Step 4, which involves setting up the payment method. Despite clicking "Save and Continue," the system doesn’t proceed to the next step, preventing me from uploading my products. My store name is "ılyartr," and I have followed all the instructions and even watched tutorial videos, but the issue persists.

This technical problem is incredibly frustrating as it has completely stalled my progress in launching my store. Etsy, I urgently need your support to resolve this issue so I can complete the setup and start selling. Please address this matter promptly and provide clear guidance to help me move forward.
