We are using smart buttons to start billing agreements for recurring payments. Suddenly, these are not working today, as there is a 403 error returned by PayPal when clicking on the button. It works in sandbox mode, but only the production is broken. The following URL returns a 403 error upon clicking the button: https://www.paypal.com/smart/api/billagmt/subscriptions/I-K1EJ6HJLCMCC/cartid (I can provide other examples for different agreements we have set up) Following this error, it throws the following JavaScript error: update_client_config_error {err: "Error: Api: /smart/api/billagmt/subscriptions/I-K1…intent=capture&commit=true&vault=true:1112:18916)", timestamp: "1595883152358", referer: "www.paypal.com", sdkCorrelationID: "c73abb55cb789", sessionID: "af38cf692f_mja6nti6mju", …} Help!!! We didn't change anything in our configuration that should be causing this.
