The issue might happen in one of the following situations:
When the SameSite cookie value is LAX, the cookie will not be sent as part of any third-party calls.
Mozilla Firefox content blocking feature prevents third-parties from tracking browser users’ activities by blocking usage of scripts and client-side storage mechanisms. Firefox uses an external vendor, Disconnect.me to provide a list of tracking sites to be blocked. Amazon Pay uses an iframe on a third-party website to return an access token after sign-in and render Address and wallet widget. With the content blocking feature, Amazon Pay iframe load requests are considered as third-party tracking requests and get blocked, resulting in the buyer not being able to proceed with checkout.
Any situation where third-party cookies or JS are being explicitly blocked by the browser.
Make sure Amazon Pay iframe requests are not blocked by browsers.
