Checkou UI Extension - Issue with first time loading checkout

Dear Shopify Team, I hope this message finds you well.

We are currently encountering an issue regarding the checkout UI extensibility on our Shopify store. Specifically, we have noticed that upon the initial loading of the checkout page, none of the extensions render as expected (image for reference).

However, upon refreshing the page, all elements of the extensibility feature load seamlessly.

We are reaching out to request your assistance in identifying and resolving this matter. It is imperative for us to ensure a smooth and consistent user experience throughout the checkout process for our customers.

We would greatly appreciate any guidance or support you can offer in resolving this issue promptly. Please let us know if there are any additional details or resources needed from our end to facilitate the troubleshooting process.

Thank you for your attention to this matter.
