Hello,
1/ To find out why thumbnail images are not loaded, try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear the cache of the browser, and check then. Maybe one of the additional plugins is the reason for the problem. 2/ https://woocommerce.com/document/shop-currency/#:~:text=To%20change%20your%20shop%20currency,store%20will%20be%20priced%20in.
