Hello spirtx,
Thank you for contacting us and for using XStore.
Please provide a detailed video of customer actions and the problem.
We can’t see the issue on your site right now – https://prnt.sc/8TqS1wBC8MLG
Please temporarily activate the Storefront theme (Appearance > Themes) and check how it works with this default WooCommerce theme.
If the problem is independent of the theme, contact the support of the WooCommerce plugin – https://wordpress.org/support/plugin/woocommerce/
Best Regards,
8Theme’s Team
