I agree. I’d switch between watch faces multiple times a day, now I don’t and I don’t like it. And the weather complication does not seem to work since installed (I haven’t tried troubleshooting but it should just work, not require any more time).
And of course, battery life is far worse now. It was a step change downward.
Not yet upgraded to 10.1.1. I saw some posts where the battery got WORSE and since my watch is a S4 I was hesitant to further change the software.
