I've found some of the interactions in watchOS 10 awkward, as though they add more friction to common actions like ending a workout requiring more clicks. Also clunky operations like when you click the action button to start a set workout like a run, it initially opens an interface showing all the workout types for a split second before actually starting your set workout. Likewise, swiping between watch faces now seeming to require a hard press and then picking one, rather than just swiping. Hopefully these are all bugs, not features.
