Hello,
What phones models, browsers and versions of browsers do you use.
We do not see the problem so it is a bit difficult to troubleshoot it.
As was mentioned, try to disable all third-party plugins that do not come bundled with our theme https://xstore.helpscoutdocs.com/article/36-included-plugins , and check how it works then. If the problem is caused by an additional plugin, you need to contact support of the plugin.
Regards
