Occasionally, when I double tap the watch to get taptic time, the watch will vibrate the hours and then get stuck. If I shake my wrist it will continue to the minutes. Likewise if I touch the watch again it will become unstuck and give the minutes, but there's no doubt that when this happens it gets stuck after vibrating the hours. It definitely isn't my impatience! This happens very occasionally and appears to be totally at random in that I can't pin down a cause or replicate the issue on demand. Anyone else experienced this one and have any ideas about it?
