Does the app work in mobile view?

Most of my customers are using their phones to visit my store. Will the app also work even in the mobile view?

Yes, the app works fine in the mobile view. Your customers will be able to see the floating button, will be able to subscribe to the product and receive a notification when it becomes available. However, this is true for Android users only at this point. We are still in the works to make this app work with an iPhone too and will be releasing it in the coming days.
