Ticket #19917 - AMP : cart always displayed as empty
I had already this issue in version 5.5.0. I had solved it disabling the AMP module.
Now that I have upgraded to 5.7.0 and that customers complain to have mobile version of the shop, I post this issue :
The AMP version of the shop seems to work fine, but when ready to pay, clicking on the Cart button shows an empty cart, despite there are items in the cart.
Also they are lots of errors in the JS console. See attached screen shots.
