Hello,
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 cache of browser and CDN cache, and check then. Maybe one of the additional plugins is a reason for the problem.
If the problem is independent of that, let me know, the problem will be passed to our dev team.
Regards
