The primary issue was that the bundles created through the initial app were not standalone products with unique SKUs or product pages. As a result, they could not be advertised separately through Dynamic Ads. This limitation hindered PrettyNamNam's ability to effectively market their bundled products.
How we achived great results
Switched to a different app recommended by Shopify, Product Bundles, which allows for the creation of standalone bundle products with unique SKUs.
Created three individual products that held inventory but were not displayed in the store.
Developed standalone bundles, including a 4-piece set bundle that acts as a standalone product and a 3-piece set bundle with two variants (1 glass and 3 glasses), named identically to the individual products to maintain consistency.
