The latest update 70.0.A.3.169 has been installed.
And the "Control from locked device" option doesn't work.
In any state of this checkbox - I can open the notification panel on the locked screen and control the phone settings.
For example, I can switch the locked phone to airplane mode. This is a huge security hole!
The "Control from locked device" checkbox should disable the ability to access the notification panel. On other phones this is exactly how it works.
