Action required: update your palpal buttons to continue processing payments

Hi,

I am using paypal for woocommerce website for one of our clients. Our client received email with link https://www.paypal-knowledge.com/infocenter/index?page=content&id=FAQ2067&expand=true&locale=en_US and something like this
“Action required: update your palpal buttons to continue processing payments”

The current version of paypal for woocommerce is the latest one i.e. 1.3.1.

Is this something we need to fix or the updated plugin resolves this issue.

Thanks
