Why doesn't my Moto 360 vibrate when I did it anymore?

[AC Question]

When I use my palm to dim the screen, it used to vibrate, which was a nice confirmation. I've factory reset, disconnected and reconnected, but can't find a solution.

Same here. Was working fine yesterday. Did all the usual factory reset etc, nothing. I'm guessing I'll have to send it back for a replacement
