We recently upgraded from Nop 3.9 to 4.3 and are now experiencing a high instance of customers attempting to configure products with attributes, and the attributes not working. Most of the time the attributes have not loaded properly on the page or the price does not update when an attribute is selected.
The issue appears randomly across multiple products. If the page is reloaded the issues is typically corrected.
Any ideas what might be causing this?
Thanks,
Lance
