Floating button changes not apply

Hello,

I have a task to move the floating button to the bottom right corner on mobile devices and to the top right corner on other devices. I changed the standard position settings for wide screens and added CSS @media rules for mobile devices. Everything seemed to be working well, but when I checked it from a device where I wasn’t logged in as an administrator at /wp-admin/, the changes weren’t applied. Even when I tried to disable this button, it disappeared only where I was logged in as an administrator. I understand that the settings are transferred via cookies, and for this reason, I can see changes only where I am logged in as an administrator. I think this is how the test mode works, but it is turned off in my settings.

Thank you in advance.
