Hello, Anand,
Thank you for contacting us and for using XStore.
1/ It’s related to the speed of the scripts loading. Elementor and our theme use scripts to apply styles, so it takes some time while necessary scripts are loaded. You can enable the site preloader (Theme Options > General) to hide that effect or try to speed up the scripts loading using cache plugin, improve server speed settings.
2/ Do you mean this https://prnt.sc/TWpMzPPmdQog ?
For this icon box – https://prnt.sc/woab25_5vdBb you can add a link to a page. Stores location you can add to the content of that page. Sorry, but we can’t guide you on what exactly plugin is used to create content from your example, because that is not our demo site.
Kind Regards,
8theme team
