PayPal Error: Currently unavailable. | WordPress.org

Hi,

Sometime in the past couple of weeks, the PayPal payment option shows on the checkout page, but as soon as it is selected, the popup tries to load, then fails and gives the error message:
Currently unavailable. Please try a different payment method.

The PayPal popup tries to load, then fails and gives the error message. Based on the browser logs errors, my feeling is this is an issue with the connection between the website and Braintree.

POST https://api.braintreegateway.com/merchants/4qvxkkvbxbfnwzv2/client_api/v1/paypal_hermes/create_payment_resource 422 (Unprocessable Content)
Error: PayPal payment options are invalid.

WordPress, theme and plugins are up-to-date, including a new 3.2.0 version of the Braintree for WooCommerce Payment Gateway plugin. Version 3.17 was also affected and rollback to v3.1.6 did not fix the issue.

Any suggestions on what is causing this and a fix? Thank you.
