Active products not showing in online store or PoS

The 10-15 most recently added products on my Shopify are not showing up on my web store or PoS. They were added to the store yesterday, are active on all sales channels and have inventory in a location able to fulfil orders, but they are not visible in the store and clicking on the View button on the product page goes to a 404.

Does anyone have any tips or suggestions for a fix?

The PoS side of things seems to have been resolved but the problem persists with 19 of the 21 products I imported via css yesterday.
