The "Schedule" option in the Google Nest app under Settings for all cameras and doorbells is currently broken. All you get is a message about using scheduling (see screen shot), but there is no option to turn "Schedule" on and off.
However, the option is still present on the home.nest.com website.
I don't even get that far. When I open the schedule panel in the app, I just get the spinning circle wait indicator.
I did find that it works on the website but requires turning on "Desktop Site" on Chrome on mobile device.
