Is there an app that exists (or some code I can add-- keeping in mind I dont do much AT ALL with coding other than very basic stuff) that will allow me to hide a specific product from a tagged customer, and also show a specific product to a specifically tagged customer ONLY whilst hiding it from everyone else that doesn't have that tag on their account?
This is a great question! Can I ask why you may want to implement this function?
You would need to add custom code to your store that would be able to hide products based off the tag. I would recommend reaching out to a Shopify Expert here at this linkor working with your developer. Shopify experts can carry out custom jobs on your store such as this for a fee.
Another option for you is to use a third party app. Here are some I found below;
Hopefully, either of those options work for you. Aside from that, how is business going right now?
