Hour on mobile

hi, I did a test on the site to check how your plugin works, it is very detailed and easy to use. On desktop it works very well, but on mobile phones the times unfortunately turn out to be many more than those indicated. The plugin is updated to the latest version, even WordPress. I am contacting you to ask if there are any further settings for mobile phones to change. Thank you Best regards
