WPS Paypal Payment returning 403 in Live Mode

Hello, I configured both Stripe and Paypal checkout method.
I tested everything in Sandbox Mode and everything was working.
I moved to Live mode, Stripe is working correctly but Paypal returns an error before the login part.

The error is:

Unable to create order{“name”:”NOT_AUTHORIZED”,”details”:[{“issue”:”NOT_AUTHORIZED”,”description”:”NOT_AUTHORIZED”}],”message”:”Authorization failed due to insufficient permissions.”,”debug_id”:”**************”,”links”:[{“href”:”https://developer.paypal.com/docs/api/orders/v2/#error-NOT_AUTHORIZED”,”rel”:”information_link”,”method”:”GET”}]}

I tested both with REST API and NVP/SOAP (legacy) API.
I tried creating a new app, but I’m still having the same issue.

Thank you
