Hi Jlhaigh,
Are you referring to using and accessing Control Center? If so, the function has remained the same "From the watch face, swipe up".
"Open or close Control Center
- Open Control Center: From the watch face, swipe up. From other screens, touch and hold the bottom of the screen, then swipe up.
- Note: You can’t open Control Center from the Home Screen on your Apple Watch. Instead, press the Digital Crown to go to the watch face or open an app, then open Control Center.
- Close Control Center: Swipe down from the top of the screen, or press the Digital Crown.
"
You can find this information and helpful details here: Use Control Center on Apple Watch
If you're having issues accessing the Control Center, test a normal restart of your Apple Watch and paired iPhone.
Restart your Apple Watch
Restart your iPhone
Best!
