 * Hi Frank
 * We are having some trouble where your plugin is causing our customers on mobile
   to be shown an outdated basket due to some caching error, also the paypal button
   is greyed out and the user cant continue, i have tried turning off and turning
   on all the settings in the backend to see if i can find the exact cause and the
   issue still occurs. The only way i can seem to fix it is clear the cache on the
   website, clear the history from my phones browser and then it works, but this
   only works once and it keeps these products in the checkout until i clear the
   cache on the website again, as you might imagine this is not viable if we need
   to keep clearing the websites cache constantly for our customers to be able to
   use the checkout.
 * Is there any chance you could have a look at this for us and see if you can find
   a solution?
 * Thanks

 * Hi Jamie;
    It looks as though Autoptimize is currently off, but I still have 
   the issue of the checkout saying “cart is empty” even if I added a product. As
   far as I can tell you’re doing page caching on Cloudflare, my gut tells me that’s
   where the problem might be.
 * Hope this helps,
    frank

 * Hi Frank
 * Thanks for your quick and helpful response, I just turned off autoptimize so 
   you probably seen it switched off, i can continue to checkout if i clear all 
   cache and history but after that the problem persists, i did think it was autoptimize
   causing the caching issue, but cloudflare could be the real culprit. I will send
   them a support ticket in the mean time.
 * Once again thanks for being patient and having a look at this, its very much 
   appreciated
 * Kind Regards

 * Well, turning off the “page rules” in Cloudflare (which is what I suppose you
   are using) should help confirming if the problem is at that level?

 * Yeah thats what we are using, i will have a look into the page rules too and 
   see if that can confirm if the problem is from there
 * Thanks
