I have just bought 2 of your payment gateways plugins and am configuring Amazon Pay right now. Unfortunately it doesn’t`work inside Chrome browser. The console says:
Widgets.js?sellerId=A2MLJ1JYAM22LS:69 A parser-blocking, cross site (i.e. different eTLD+1) script, https://static-eu.payments-amazon.com/v2/login.js, is invoked via document.write. The network request for this script MAY be blocked by the browser in this or a future page load due to poor network connectivity. If blocked in this page load, it will be confirmed in a subsequent console message. See https://www.chromestatus.com/feature/5718547946799104 for more details.
