GCPW & Guest Access

[Osama_Yunes]

Hi 
We setup GCPW in our Windows Laptops. It's working very good and all the policies applied then suddenly we find that the users at the OU were able to access chrome through Guest and it's blocking in User & browse settings as well adding other profiles, not from our workspace is bloked as well.
Now the users can access their windows as normal but the policy of the Guest mode is not applied and adding other profiles.

Anyone face something like this and know the resolution for this.

Thanks
