How To Troubleshoot Tap Gesture Not Working Issue On Apple Watch?

To troubleshoot tap gesture not working issues on an Apple Watch, follow these steps:

1. Ensure your Apple Watch is running watchOS 10.1 or later, compatible with the double-tap gesture feature on Apple Watch Series 9 or Apple Watch Ultra 2.
2. Make sure the watch is unlocked and fits snugly on your wrist.
3. Confirm that you're using the correct gesture: Tap your index finger and thumb together twice quickly and firmly.
4. Enable the Wake on Wrist Raise feature in the Watch app on your iPhone, under Settings > Display & Brightness.
5. Check if Low Power Mode is disabled, as this disables double tap.
6. Verify that your Apple Watch isn't paired as a Family Setup Watch.
7. Make sure double tap is enabled. On your Apple Watch, go to Settings > Gestures > Double Tap, and toggle it on.
8. If the double tap icon shakes from side to side, the gesture might not be available for that screen or third-party app.
9. Restart your Apple Watch: hold down the side button until the Power Off slider appears, then drag the slider. Once off, hold the side button to turn it back on.
10. If the issue persists, force restart your Apple Watch: hold down the Digital Crown and side button simultaneously for at least 10 seconds until the Apple logo appears, then release.
11. Check for watchOS updates and install them if available.

If none of the above steps resolve the issue, it could be a hardware problem. Contact Apple Support for further assistance.
