Change my name on my activities app

Hi - try these steps:

• On your iPhone, in the Contacts app:

  Check that your contact card contains your name (as you wish it to be shown), Apple ID email address and phone number.

• On your iPhone, go to: Settings > Mail, Contacts, Calendars > in the Contacts section, check that My Info is using your contact card.
• On your iPhone, go to: Settings > General > Siri > My Info - check that your contact card is selected.
• On your Apple Watch: ask Siri "what is my name?"

After making any changes:

• On your iPhone, in the Watch app, go to: My Watch > General > Reset > tap on Reset Sync Data.
• Nothing will seem to happen, but the process will run in the background (invisibly to the user), so allow a minute or so.

It may then also help to restart both your iPhone and your watch. Turn both devices off first, then restart your iPhone before restarting your watch:

• To turn your watch off: press and hold the side button until you see the Power Off slider; drag the slider to turn off.
• To turn it back on: press and hold the side button until you see the logo.
