As long as we’re on anecdotal evidence, I’ve found that the repeated calibration failures eventually go away and don’t seem to be tied to any particular variant of rubber chicken waving. Sometimes I’ve logged out of the app (which makes no sense calibration should be happening independent of that), other times I’ve turned it off and taken a 5 minute break, and still other times I just keep at it and by the third or fourth attempt, it works. Usually the magic trigger to make it work is setting up a camera so I can capture the failure. I still haven’t managed to get it to do the orange light while being recorded.
I suspect this is one of those situations where we are all seeing connections that don’t exist. As far as I can tell, the only official response has been to turn it off and move the head under the camera.
Also, soft power with a toggle switch? If they did that, it would irritate me even more than the delays.
