    If other fixes aren’t working, you might need to force restart your devices. For good measure, restart both your Apple Watch and your paired iPhone. Here’s how to do it:
    • To restart your Apple Watch hold the side button and Digital Crown down at the same time until the Apple logo appears. This may take about 10 seconds.
    • The right way to hard reset an iPhone depends on the model. For most newer iPhones (iPhone 8 and later), press and release the volume up button , then press and release the volume down button , then press and hold the side button . Release it when the Apple logo appears.

Unpair and re-pair your watch and iPhone.
