Hi y’all!
The developers of our Delivery Date Schedule came up with a solution on their side:
Customer cannot leave without picking a delivery date
Express Payment options are not displayed here.
One has to click “Zur Kasse” = go to checkout to see these options.
Why this again?
Because when Express Payment options are displayed here, and customer does NOT pick a delivery date and, let us say, chooses PayPal Express Checkout it can be done, however cart comes up empty and payment goes through.
Weird.
Anyway, the next step displays Express payments and with delivery date it works.
I hope that helps.
Best regards,
Urs
