Is anyone else experiencing intermittent issues with the haptic feedback/vibrational alarm on Apple Watch? My wife and I both leave our Apple Watch on silent and sleep with them in airplane mode, using the vibrating alarm to wake us up. At least that's the plan—the problem is that the alarms don't always vibrate, which as you can imagine is a big problem. We will literally watch the alarm screen appear on both of our watches at the time of the alarm with the option to Snooze or Dismiss—but no haptic feedback whatsoever. Although it works sometimes, we've been late to more than a few appointments and missed a flight before realizing the problem wasn't user error. We originally assumed we forgot to set the alarms, but now that this issue repeats and we can watch it happen—this morning for example—we wanted to see if any of you have experienced this and/or found a solution. Devices + Conditions: iPhone 6s Plus (128 GB Space Gray & Rose Gold) set on Do Not Disturb Apple Watch (Stainless Steel & Space Black) set on Airplane Mode (to preserve battery) The fact that this happens on separate devices in recurring frequency leads me to believe we cannot be the only ones out there experiencing this problem!
