My app is approved by Shopify today. It also has a free option, that helps merchants to send back in stock alerts via Whatsapp. Happy to share it with you all.
Congrats! I liked the graphic on your app listing. It seems you're professional. If I were you, I'd add my intro video asap.
Wish you a fruitful journey on Shopify.
