I am working on a Amazon Pay/ Login with Amazon extension for the WooCommerce platform. In anticipation of Google Chrome enabling Cooking with SameSite by default in Chrome 80.
We tested our integration by enabling the flag at chrome://flags/#same-site-by-default-cookies . With this flag enabled our integration broke completely with the error.
"To complete the Amazon Pay checkout you must accept third-party cookies in the options/settings of your internet browser. After you have accepted third-party cookies please refresh this page to continue check out." In the address list widget.
It seems there's nothing we can change in our integration to make it work properly as the important cookies in the amazon.com domain need to be set with the "SameSite=None" attribute for the widget to work.
Is there plans to support SameSite cookies in the near future.
