Mostly for me it’s just awkward and unintuitive. I’ve never been a big fan of using the side buttons; the swipes, especially for accessing the control panel, felt natural before watchOS 10. Now it just feels the same way that accessing the control panel on the buttonless iPhone does: weird and out of place.

And also, having to long press to switch between watch faces is just downright annoying. There should really be an option to revert back to the old way.

Apple made these changes in watchOS 10, and as far as I know, there’s no way to change them.
