Since I got my Applen Watch (April 24th) it crashed (or / and) powered off spontaneously for six times. At first it always happened late in the evening. I wanted to check the time, but the watch was powered off. The last time, which was a few seconds ago, I wanted to check the weather. The watch hang up and then powered off. I already did three resets, but no improvement. Does anyone have the same issues?
