"add to cart" button doesn't work when I react too fast when entering the page &switching variations

[PowerfulFlame]

Hey guys, I am having this issue when the "add to cart" button does not work if I react too fast to the variations, then when I refresh or go to my homepage, and come back to the product page it works just fine

Now I talked with Shopify live chat support, and they some how fixed the computer version, but 98% of my customers are phone-based so it doesn't quite help.

I am hoping I'd get help from a Shopify expert in such cases

Thank you so much for your attention and participation.
