 * Hello,
 * I have some problems with activated REDIS Cache and Amazon Pay Plugin. This only
   happens on small viewports, when Amazon uses the Return Url in the checkout for
   customer login. On larger screens a popup appears and all works.
 * After login with amazon and captured billing and shipping information and click
   on “place order” and error appears “Error: Order missing Amazon order reference
   ID”. After clicking again on “place order” nothing happens. In the backend from
   amazon an order is created and also woocommerce creates the order with status“
   pending payment”. Now, we can click on “capture” in woocommerce to receive the
   money from amazon, but for the customer in the frontend it seems that something
   went wrong.
 * Is there a way to exclude the amazon plugin from redis cache? Or anybody else
   with the same problem?
 * Thanks and regards,
    Alex

 * Hi Alex,
 * yeah you can ask the Amazon Payments support team for the cache groups they are
   using and ignore them. More about that in the readme.
 * However since the error is only happening on mobile, it might be a bug inside
   Amazon Payments and how they are using the `wp_cache_*` API.

 * Hi Till,
 * thanks for reply.
 * After a long discussion with them, the only I answer I get is that they don’t
   use anything that could conflict with caching…
 * The only “helping answer” is to exclude the checkout and thank-you page from 
   caching, I seems they don’t know how object cache works.
 * After testing with different Caching Plugins and all time the same issue with
   that payment method on mobile, I’m sure it’s their fault in the plugin.

 * Why don’t you email me the source code of the plugin and I’ll have a quick look.
