We're encountering significant challenges in launching our new products due to unforeseen complications in achieving proper ranking. The current issue stems from the separation of BSR ranks across parentage and the individual ranking of child ASINs. Despite offering 8 variations, each child ASIN is ranked independently, hindering the recognition of the parent product.

In an effort to resolve this issue, I've experimented with deleting and relisting the parent product, briefly resulting in shared ranks for a day, coinciding with an improvement in sales. However, this improvement was short-lived as overnight, the ranks reverted to ranking the children individually, leading to a plateau in sales once again. Despite opening multiple tickets, support has only advised that the issue is resolved and to wait 24 hours for changes to take effect. Category, website display group, and GL are all identical, leaving me uncertain about further steps. All our other parentages share ranks without issue. Is this a new occurrence with newly created listings? It's nearly impossible to properly index and rank with this method, with sales solely generated 100% by PPC.
