I have an issue and I have talked to Shopify and they do not have the capability to do what I want to do and said I would need to find an app.
This is my scenario:
99% of my products will all share three variants: size, color, sleeve length.
I need to add an option of black to my color variant. I found an app to achieve that, but now I want to bulk add the black image to the black option for all the products and I am having issues finding an app to do this.
I will also be exceeding my 100 variant options per product with my next addition and need an app that can let me expand the number of variants for each product.
I understand your problem. To bulk update the product variants you need an app. we can help you with a custom script that can do these updates for you. Let me know if we can do this for you.
