Hi DynamicWeb,
After I upgraded version from 8.3.1.8 to 8.4.1.6 I have an issue with "Product catalog (ecom)" module templates.
Templates I have defined: List, Groups and Product.
Everything was working berfore upgrade and now it is always showing me List template when I am on a Group page. Product template is working fine.
Please see attached screenshot of webshop module.
Thanks
