I haven’t tried it yet, but with past Betas, I usually would not head into them at this point, too much risk it would have work-day impacting bugs but if it’s stable maybe I’ll give it a try. I really want to try WatchOS and you can’t do that without iOS
I found Siri suggestions to be such a pain I gave up on them and just swipe down for control center, tap home and use those buttons.
