While enabling pre-orders based on the inventory location (warehouse) is convenient, this feature remains an app limitation.
Currently, our app will check the available stocks in all locations and not per location. So even if it is 0 on one location and there is still stock on the other location our app will detect that there are still stocks.
We understand this feature can be useful, but we may have plans to include it in a future update. If you have any other questions or need help with different features, please don't hesitate to contact our support team. We are here to help!
