Nest Protect flashing yellow light

Community Member

Carbon Monoxide alarm went off, everything clear but all sensors still blinking yellow light. How do I reset system or get alarms throughout the house to stop blinking yellow?

Any traction on this issue?  I’ve seen this same post elsewhere and here, with no resolution. I have the same issue. CO event and everything is green in the app but the protects are all still pulsing  yellow.  If you press the button, they just reiterate the CO warning despite it having passed.
