 * Hello [@kaboemnld](https://wordpress.org/support/users/kaboemnld/)
 * Thank you for reporting this.
 * I have forwarded these to our developers for review. These appear to be PHP warnings
   and deprecation notices rather than critical errors. They should not affect the
   checkout flow or the functionality of Apple Pay.
 * We’ll investigate whether any code changes are needed to address them in a future
   update.
 * Kind regards,
   Krystian
