CORS error with Braintree Drop-in and Paypal

I am having bad times implementing braintree’s drop-in due to a CORS error when I try to use its PayPal integration.
It does work with a sandbox account, but it doesn’t if the same code points to a Braintree production account.

Has anyone faced the same issue? I cannot find any working capacitor plugin for the latest version of capacitor v3.0 and Ionic Vue, so I am stuck with the web version
