Site on wordpress woocommerce. When you log in from an iPhone, nothing happens when you click "Add to Cart". The burger menu works, the "enter" button in the header too .. I go from android and everything seems to be ok, it also works in the iPhone emulator, everything is ok in the emulator in the browser .. I don’t understand where to dig and what’s the matter. From two iPhones one and also, press the button and effect 0. Tell me what's the matter?
Here is the actual screen recording from the iPhone where the problem is clearly visible -

Answer 1

Assumptions 2 (IMHO) - either the built-in Apple browser blocks some things on an insecure connection, or there are not enough meta tags (for Safari, something is added to meta in Safari, 0 I observed this).
