Back In Stock Alert‑ Notify Me

I am selling products that are available at a specific time, so I am using the Coming Soon Feature from the app.
The app works well for this as products can be visible already in the shop. A feature that is not provided by Shopify natively.

The support team is very responsive.

For the moment it is no working for the sales Channel FB/Instagram. but the team promised they are working on this to add other sales channels.
