Hi @donzzzzz, thank you for reaching out. The thing is, the Apple Pay/G-Pay is not compatible with our Order Delivery Date Pro plugin right now. We had a user report this a few months back, and we spent a lot of time fixing this compatibility issue, but unfortunately, it is not technically feasible at the moment.
The main problem, there is no way to add a custom field to the checkout popup form that Apple Pay / Google Pay creates. In other words, the Payment Request API used by the payment gateways does not provide any options to add the custom fields in the payment popup. Instead, they only provide Name, Email, and Phone fields for the Contact Info section and accept only the shipping address and methods. Here is a screenshot for reference — https://www.screencast.com/t/fax6eg6M. Here is the link for the Payment Request API: https://developers.google.com/web/fundamentals/payments/basics/how-payment-request-api-works.
However we will revisit this sometime later, but for now, I’m sorry our plugin isn’t fully compatible with Apple Pay/G-Pay.
