It has taken over 2 hours of constant attention to get the watch to pair w phone and download the watch update. At each step, I had to restart the watch and in the nanosecond between the fitbit logo and the big red X reappearing, I had to get the phone bluetooth to first forget the watch, reconnect on Bluetooth and twice download the update. On both updates, it ended with a failure message. However, after the second failure, the watch did start to function again. I'm going for a walk know to release the tension that built up during the process. I'm afraid to try the update again, because at lease now I seem to have watch functioning again.
