AMP: Accelerated Mobile Pages / Problems
AMP Page Item Being Ignored
Did assign the AMP page item to the page?
Did you put the AMP item code at the top of the page?
Did you check to see if your product or category is using an alternate page? If it is, make sure you include the AMP item and page items on the alternate display pages as well. This is a common reason for AMP pages not showing up.
