Can't add products into a cart

[lore143]

Joomla: 3.9.15.
VirtueMart 3.6.10
PHP version 7.1

Good morning,

I have such a situation, I use the mobile menu module https://www.joomforest.com/joomla/extensions/jf-mobile-menu  , and when I enable this module, can't add products in the cart, but when I disable it, everything works well.
and that happens only when I view the site on my iPhone,
please advise how to fix it

Many thanks!

You have a JS conflict due to this module. Talk to the designer of the module.
