“Custom Script” setting inside the SP admin center is been ignored for modern sites

[john john]

I did many tests and reading and i did not find a clear answer if the "Custom Script" setting inside the sharepoint admin center affect modern sites (Communication or Team sites) or not. for example i did this test:-

1. inside the sharepoint admin center >> settings >> Custom Script >> i enable custom script as follow (i did this around 7 days ago):-

2. then if:-

   • I (as the office 365 and sharepoint admin) create a modern site (communication or team)
   • OR any end user directly create a communication modern site or team modern site
   • OR and end user create an office 365 group.

the generated sharepoint modern sites will always have custom script disabled. so can i conclude that the "Custom Script" settings inside the sharepoint admin center does not affect modern sites (Communication or Team sites)? and when the setting mentioned "self-service created sites" this does not cover modern sites created by end users or created through creating office 365 groups?

second point , inside this official documentation Allow or prevent custom script it mentioned the following "If you change this setting for a user's OneDrive or a classic team site, it will be overridden by the Custom Script setting in the admin center within 24 hours." so why this is not happening in my case? i mean why the SP admin center setting (custom script is enabled) did not override the modern sites settings (which have custom scripting disabled)?

Thanks.
