why would someone's location not update

Someone's location might not update for several common reasons including poor GPS signal, weak or unstable internet connection, location services being turned off, sharing time limits expired, the device being offline or turned off, or system glitches and bugs affecting location apps like Find My or Google Maps. Other factors include the device being in low power mode, privacy settings disabling location sharing, or the app not refreshing properly in the background. Troubleshooting steps include checking that location services and permissions are enabled, ensuring a strong internet connection, restarting the device or app, toggling airplane mode, and verifying that location sharing settings have not been changed or expired.
