I activated ApplePay in Stripe (express checkout) . I booked a seat and paid with ApplePay. All went fine, but the order itself show up in Woocommerce as “non-ticket” order. In EventOn ticket orders it does not appear at all, and the seat is marked again as available.
In the meantime I deactivated ApplePay again, but this is a great payment method and it should work correctly.
