Hi Andrei,
as described, there's a lack in tje logic used by NopCommerce with Best sellers, Also purchased, etc. product extraction.
NopCommerce analyses ONLY single products, and don't consider that grouped product are outside
all flows. What i mean is simple: GROUPED PRODUCTS cannot be sold, you sell their VARIANTS This means that if I want to search “Also purchased” starting from a grouped product, I won’t see nothing. Instead I need to rank “Also purchased” of related variants and then return grouped products of these variants.
Is it possible to fix this bug?
