Issue with Receiving Custom CSS Code from the Server

[MBZ]

I’ve made some desired changes using Custom CSS, but these changes are only applied to the server panel. 
Is there a way to have these changes applied directly to the clients from the server as well?
I know there is a Custom CSS code option in the client panel where I can manually enter the same code to achieve the desired result, but doing this on many clients,
especially if they are Android boxes, is very difficult. Also, the "Disable Server-provided custom CSS Code" option has not been checked.

In the web-client or Jellyfin Media Player, if you click your User icon, then Display, you will find the client CSS box.
This applies CSS to only the client (and as you've seen, there's an option to disable Server CSS)


But, if you click the 3 lines (hamburger button) next to the JF logo and go to Dashboard, then General
This applies CSS to all clients on the server, unless they enable that option to disable Server CSS
