Why is one of my products missing from its category page?

Check these in order:

1. Status: open the product under Products → Products. The Status card must say Active. Draft, Pending approval and Rejected products are not shown.
2. Category: in the Organization card, the exact category must be selected under Categories. Selecting only a subcategory does not show it on the parent category page.
3. Stock: if it is out of stock and Show out-of-stock products on the storefront is off (Products → Inventory → Inventory Settings), it is hidden from listings.
4. Plan limit: if your store has more active products than your plan allows, the newest ones are hidden.
