The pon app on the Apple Watch is stuck or not updating — what helps?

Usually it helps to bring your iPhone close and briefly open the Watch app so it syncs up. If that doesn't help, force-quit the app on the Watch once and reopen it:

• Open pon on the Watch.
• Press and hold the side button until the power-off menu appears.
• Release the side button, then press and hold the Digital Crown until pon closes and you return to the watch face.
• Open pon again — usually everything runs smoothly after that.

If even that doesn't help, restart your iPhone and Watch; stubborn sync hiccups almost always clear after restarting both devices.
