On the evening of Tuesday October 2 2018, there was an apple watch update. I performed the update. I had had my watch for one week and one day with no problems. After that during the morning hours, either once or twice a day, the fall detection feature has gone off. I for the most part have been moving aroudnt e kitchen fixing breakfast or doing some other task. yesterday it went off twice, once at six a.m. (in the kitchen) and 11:09 a.m. quietly sitting on the couch reading a braille magazine. I have been working on this with apple support. I feel somehow it is related to something that was done in the update. I am soliciting feedback if anyone else has encountered this problem. Thankfully, except for yesterday when the watch battery was very low, i was able to cancel the alarm, but yesterday battery was too low to tell. i did call 911 and let them know that i had attempted to stop the alarm and to disregard if it had not been successful. any feedback would be appreciated. thanks.
