My Instinct 2 Solar sometimes has continuous vibrating. Meaning, I will get a notification, and when it is supposed to be a short vibration alert, instead my watch will vibrate non-stop. So far, the only way to make it stop vibrating is by turning it off and back on. My first thought would have been that I have a faulty watch, but I actually had the Instinct 2 before switching to the solar version. I had this exact same thing happen to the Instinct 2. Does anyone have any ideas as to what the problem is?
