Activity and Health app not syncing

Hello,

Looks like I have a problem with the Activity app and the Health app.

The two do not sync, so the following problem arises:

In the Health application I have a number of steps of 2000 for example and on the Apple Watch I have only 15.

What I mean is that if I leave my watch on charging and take 5,000 steps with my phone in hand, these steps won't sync to the Activity app on the Apple Watch.

I followed the steps below:

"On your iPhone, go to: Settings> Privacy> Motion & Fitness - check that both Fitness Tracking and Health are enabled.

On your iPhone, in the Watch app, go to: My Watch> Privacy> check that both Fitness Tracking and Heart Rate are enabled.

Close certain apps and then restart (normally) both your iPhone and your Apple Watch:

Close the Watch app, Activity app and Health app (if open) on your iPhone:

Double-click the Home button, then swipe up on each app preview to close the apps.

Turn both devices off together, then restart your iPhone first "

I also reset the Apple Watch and unpair it.

Please help me, it's very frustrating.
