Hi Niklas
PayPal CHECKOUT is working fine thankfully, so I’m gonna stick with it as long as I can.
The error message my customers were getting with PAYMENTS was,
[UNPROCESSABLE_ENTITY] The requested action could not be performed, semantically incorrect, or failed business validation. https://developer.paypal.com/docs/api/orders/v2/#error-MISSING_SHIPPING_ADDRESS
Best regards
