Bulk Add To Cart not working properly on iOS

UPDATE:
Caused by a race-condition that is more noticeable on iPhones, Wix team is aware of it.

Hi, I have an issue with adding to cart multiple items at once, only on iOS.
At first I used the charms example from the mega store, but iOS users seem to be able to add just 1 item and not the second one (it doesn’t matter which is which, only the first product I send is added to cart).

Same issue is happening in Wix’s Charms example too: https://www.wix.com/code-examples/bulk-add-to-cart-vw with an iOS device, the charms are not added to cart.

The problem doesn’t happen on Android or any desktop browser.
I’ve tried both with async/await and Promise-based requests.

I suspect that the 2nd request is not being made because on mobile the user is redirected to the cart page…

Any ideas?

EDIT:
I can replicate this issue on Desktop as well, but its less frequent as in iOS.
