I just got my SE2 and updated it immediately to OS10. The control center only opens via power button not the swipe up which is I prefer. I already force restarting, power off and changing watch face nothing works. Will appreciate all the helps. Thank you!
Update: I just found a video regarding the update after posting this. Thank you all!
this confused me too but then i found out they changed it in watchos 10, i adjusted to it pretty quickly so i didn’t care that they changed it
