1. Have a bug with cart on some devices. (Android 12 640×320) add to cart looks like broken. Attach screenshot.
2. Need to add some additional specs on product archive like on second screenshot. Is it possible to add something like that via wp backery or something like that. If not could your specialists develop this on a fee-for-service basis
1. Seems that right now the mini cart comes from Elementor so in order to disable it, navigate to Elementor -> Settings -> Integrations and set the “Disable” value: https://take.ms/Ra7Cv
2. Sorry to say but right now there is no option in Theme Settings available for that. It requires Customization and this is beyond our limitations and support policy scope. Hope you can understand our limitations.
Let me know if you have any questions or concerns.
