Accelerated Checkout Buttons Now Support Functions

Themes

We have improved the design and function of Dynamic Checkout and Accelerated Checkout buttons on storefront pages. Checkout buttons now support Functions, provide better performance and a smoother user experience. Button styling has been enhanced, and skeletons have been added to prevent layout shifts during page loading. Some customized themes may be impacted by these UI updates as a result. These improvements are actively rolling out to merchants who have migrated to Checkout Extensibility.
