Why does the notification link appear on a product page even if only a variant of the item is out of stock?

Question: I noticed that the notification link to send an email appears on the product pages even if the product has multiple variants and only one of them is out of stock. Why is this so?

Answer: Unfortunately, this issue happens due to the incompatibility of the app to some themes. When a product has several variants such as colors, sizes, styles, etc and one of them gets out of stock, the app detects it in general. We are currently working on a fix to resolve this issue.
