Chrome Website Isolation with Group Policy

Im currently testing the following Group Policy from the Chrome admx Template.
This policy should deactivate or activate the Website Isolation setting for Chrome. The Registry key is changed / applied but it has
no effect in the Chrome settings. I tried it in User and Computer Configuration and with restart.
Has anyone else tried to apply this setting and experience the same issue or has any idea what could be the problem?

Enable Site Isolation for every site

Data type:
    Boolean [Windows:REG_DWORD]
Windows registry location for Windows clients:
Windows registry location for Google Chrome OS clients:
Mac/Linux preference name:
Supported on:

        Google Chrome (Linux, Mac, Windows) since version 63
        Google Chrome OS (Google Chrome OS) since version 63

Supported features:
    Dynamic Policy Refresh: No, Per Profile: No

    NOTE: This policy is experimental and may break functionality! You might want to look at the IsolateOrigins policy setting to get the best of both worlds, isolation and limited impact for users, by using IsolateOrigins with a list of the sites you want to isolate. This setting, SitePerProcess, isolates all sites. If the policy is enabled, each site will run in its own process. If the policy is disabled, the pre-Site Isolation process management logic will take effect. If the policy is not configured, the user will be able to change this setting.
Example value:
    0x00000001 (Windows), true (Linux), <true /> (Mac)

Hi Manuel.

Where are you looking at in order to verify that it got applied? I'd look at the site chrome://flags/ and there, search for isolation.
Also make sure that your chrome is indeed at version 63.

Chrome version is 63.

I checked if the registry key mentioned above has been set and it changed according to how i set the policy but its not applied in the browser itself.
Do a reverse check: take a virgin installation of chrome, set that within the browser at the flags site and see what registry setting it sets and compare.

I already tried that with regshot but couldnt find any relevant changes to the registry.
Look, I could reproduce that at home, later on. I will send me a reminder.
Reproduced. Policy sets the regvalue, but I cannot find it in chrome's settings or flags dialogues, but honestly, I am not sure where to look.
Where should it be found? Only found this docu:

1 " it has no effect in the Chrome settings" - again: where did you look at to verify?
2 in my link, there is a process described to verify the effectiveness - did you use it?
