Yeah, I let my 7 plus update overnight and I updated my series 4 watch today and all four TVs to the current OS’s today. iOS14 works fine. The App Library is as useless as I thought it looked in reviews and I had to disable “Private Address” in my WiFi settings because it causes more problems than it fixes. Overall, a solid update so far.
It is nice, but it doesn't kick in right away. From my experience, I lose a good couple of seconds before the watch recognizes the water and hand rubbing.One more thing then I’ll be quiet and go watch the newest episode of The Boys... the 20-second hand washing timer for WatchOS 7 is nice. You have to turn it on in the watch app first, since it’s disabled by default.
