I created products in HubSpot but even though I have two-way integration enabled, the products to not sync to Shopify. I had to recreate them in Shopify and then import them into HubSpot.
It would make more sense to have the products sycn both ways or at least allow exporting to Shopify. Without this, we're doubling the work we need to do.
In addition, Shopify products can't be used in quotes either, which means we have to create separate product lists in HubSpot to use in quotes.
