Paypal credit cards button not working

Hi,

We bought Event Ticket Plus with event calendar to manage our event registration. Our theme is Go but we also test and get the same issue with Theme Twenty Twenty.

We set up a Business Paypal Account and follow the guidelines to connect Event Tickets Payment to Paypal (IPN, Order completed page, etc.).

We set up a sandbox account with Paypal to test our with Event ticket. In using the sandbox account, only the Paypal button is appearing in the checkout page and the whole process is working with Paypal account or credit card within a Paypal account.

We we go live with our Paypal account, we have the Paypal payment button and the credit card button on our checkout page.

But the credit card button is not working, we receive a 422 error from Paypal:

Issue COMPLIANCE_VIOLATION

The requested action could not be performed, semantically incorrect, or failed business validation.

We saw a difference in our Paypal API credentials page bewteen the connection of Event Ticket to the sandbox and our live account:

• Advanced credit and Debit Card Payments is activated in our sandbox integration
• and not in our live account

could you please provide us some support? Thanks in advance
