Why award is not awarded after fulfilling the requirements?

Good morning iyim77!

Welcome to Apple Support Communities! It sounds like you've completed a challenge, but the achievement is not reporting correctly. It's important to have your Apple Watch report its information correctly, so I'll be happy to help out with this.

Keep in mind that it can take up to 9 days for an Activity award to show up: Earn Activity awards using your Apple Watch

If it's still not showing up, take a look at the steps here to help increase the accuracy of your Apple Watch: Get the most accurate measurements using your Apple Watch - Apple Support

Have you also tried restarting both your Apple Watch and your iPhone, as well as update each device? If not, do that now:

Have a great day.
