It try Social Share for WooCommerce . Is there a way to add an Instagram button?
Thank you. Robert
I hope you are doing well today. Unfortunately, Instagram currently doesn’t allow you to share a photo or video from another website – you can only upload photos/videos directly from your mobile device.
Since there isn't any sharing mechanism, there isn't any way for us to include a button that will share your content on Instagram.
I hope this explanation will help you to understand the situation.
