Just created two new inventory items and added 3 related products to each. When I view the products in the store, I don’t see the related products I setup. I go back to view the inventory items, select the ones I created, look at ‘Related Products’ and none of the selections I’d previously made and saved are being retained.
are you sure that you test with a correctly theme with updated files? Have you solved your other issue? Maybe this current malfunction is depend on it.
I’ve not idea what caused it and in the end my only solution was to reinstall. I hope you manage to solve it ok. Seems there’s a lot of work to be done to ensure smooth upgrades of Magento.
