Clearing All Notifications
After you had collected a lot of notifications on your Apple Watch, a Force Touch gesture offered a handy way to clear them all out simply by pressing firmly on any one of them to reveal a “Clear All” button.
In watchOS 7, of course, the gesture no longer works, but you can find the “Clear All” button by scrolling to the top of your notifications screen. It’s less convenient, especially for those who have developed muscle memory for clearing notifications, but at least it’s still there.
You can also still clear individual notifications by swiping to the left on a single notification and tapping the X that appears.
