Click on each button in sequence from top to bottom without refreshing the page. Each button (except the 'Done' button) will bring up the Payment Request UI window.

2. Change your Shipping Address - either update your existing one by changing something (name, address, etc), or select a different Shipping Address, or add a new Shipping Address and select it.
3. Go back to Shipping Method, and there is now an option called "Dynamically added shipping option". Select it
4. Click on the 'Done' button

• When the address is changed, shipping methods can be updated
