My new Apple Watch Ultra's screen doesn't like the rain. I have had my Ultra for about three weeks, I use it exclusively for running, twice I have been out running in the rain, the first problem started with starting and stopping playing songs while using my running playlist in Music. I was out today in heavier rain and as soon as the screen got wet it wouldn't respond at all. Never had any problem with my Series 6, surprised with this given how it has been marketed as a tough adventure watch!
