Hi there,
Thanks for the feedback.
It looks like your site is using the new Cart & Checkout Blocks, which are not yet supported by PayPal Payments.
Block support for PayPal Payments is currently in development and will be released over the next couple of feature updates. You can find more details and get notified of relevant updates?here on GitHub.
The first parts of the Block support are expected to be available for testing with the next feature update later this month. If you’re interested in providing early feedback, you can also get in touch with the support team directly.
Thanks!
Kind regards,
Niklas
