Make sure that pre-order is enabled and status is displayed for the product / variant in the app.
If the app displays other status then pre-ordering is not available because of some conditions:
- Pre-order limit reached (configure in the product / variant settings)
- Current date doesn't match pre-order schedule (configure in the product / variant settings)
- There are still several items in stock.
The pre-order button is displayed only if the quantity of items in stock is less than or equal to zero. |
