What should I do if watch upgrade fails?

1) On the upgrade failure page, tap the Retry button to upgrade again.
2) With the watch connected, manually swipe down on the status home page to sync data, and watch upgrade will be triggered again.
3) Disable and then enable Bluetooth on the phone, and restart the app to connect to the watch for upgrade.
Note: When upgrading the watch, ensure that the power of the watch remains above 10%. Upgrade will fail if the power is lower than 10%.
