I'm trying to upgrade 2 J2Commerce 4 websites that use the Grouped Products app so a single product article can display different products in a table with quantity option and add to cart button. See https://www.quintessentialquilting.com/shop/notions/pre-printed-grid-practice-panels One of these products is a combined product of all 4 of the other products. I'm trying to reproduce this in J2Commerce 6. I found a bundle product app that will create the combined products, but it won't add all separate items to a single add to cart option. It seems the bunded product app isn't what I need at all. How do you render this set up in J2Commerce 6? Is this possible?

Thanks!

I purchased Group Product app and installed it. Immediate failure! the moment a product's type is changed to Group Products, both the admin edit form and the frontend product page turn 500 fatal error. Bug report submitted in Technical Support / Bugs.
