Web doesn’t working with ios

Hi guys! I need help with this issue. I create a website with woocommerce, but there is a problem and only showing up on IOS Apple.

The problem
– there is minimum quantity to add items to cart. I try in pc and android, they working well. But when i try adding 3 items in IOS, an error showing up that tells “Minimum 3 items to add in cart”.

I have tried to disable all plugins and change the theme, but my website became a mess. I think because WooCommerce Composite Products plug in. But when i try to disable and enable again, there is no change at all.

Thank u for your help
