When on any product page, if you click the Compare link, it may work initially, and you can then view the comparison table. However the loader button never changes to the checkmark. And once you go to the comparison table and then back to a single product (that is already in the table) and click Compare again, it will not load. And there is no indicator that is already in the comparison table so a customer may not remember. And in my experience on my end, it will then not work when I click Compare on any other product either. So once the hangup occurs no more products can be added.
