Lost days for longest move streak :(

Greetings vanessafrombeaumont,

Thanks for posting in the Apple Support Communities.

We understand you've noticed that your move streak has reset unexpectedly, so let's check into a few things together.

We'd first recommend confirming that both your iPhone and Apple Watch are up-to-date with the latest supported software version. To update your Apple Watch, you'll first want to be sure the paired iPhone is updated. For assistance with updating your iPhone, check out this resource: Update your iPhone or iPad - Apple Support

Once you've confirmed your iPhone has the latest iOS version, use the following steps to update your Apple Watch: Update your Apple Watch - Apple Support

Update directly on your Apple Watch

If your Apple Watch has watchOS 6 or later, you can install subsequent updates without your iPhone:

1. Make sure that your watch is connected to Wi-Fi.

2. On your watch, open the Settings app.

3. Tap General > Software Update.

4. Tap Install if a software update is available, then follow the onscreen instructions.

Once both devices have the latest software version, compare the information shown on your iPhone in the Fitness app with your Apple Watch to see if the awards and data match. Let us know if they match or not, and specify what is shown in both places. For assistance with locating the awards on your iPhone, take a look here: See your activity history, trends, and awards - Apple Support

We look forward to hearing if this has cleared up for you, and be sure to provide additional details that were requested if you need additional help.

Have a great day!

Vanessa,

Thanks for keeping us updated on how this issue was resolved.

We're glad to see that you data is back now so you can continue to add to your streak.

Have a great day and let us know if you have any other questions.

Take care!
