Apple Watch Ultra Workout app: No data after watchOS 26.2

Apple Watch Workout Not Recording Data After Installing watchOS 26.2

After updating my Apple Watch to watchOS 26.2, the Workout app no longer records activity data properly.

I can open the Workout app and start an activity as usual, but during and after the workout, the following metrics remain at zero:

Time
Elevation
Active calories

Heart rate data is recorded and displayed correctly.

My device is Apple Watch Ultra (1st generation).

The issue started immediately after installing watchOS 26.2. Restarting the watch and phone did not resolve the problem.

Has anyone else experienced this issue, or found a solution?

Additional Finding

I noticed that tapping Start on the main Workout screen does not actually begin recording, even though the workout appears to start.

However, if I swipe right to bring up the End/Controls screen and press the Start button there, the workout begins recording correctly and all metrics update as expected.

Is this behavior expected in watchOS 26.2, or is this a bug?

To rule out a software issue inside your backup data, erase the watch and pair it again, setting it up as a new device. You will only lose your created Watch faces and may have to activate the cards in your Wallet app again.

Then test the workout app.

I had similar issue, with glitch on workout data fields - seems like some metrics HR/Total time and avg pace are hidden - what helps is to switch data page, or wait for watch to screen off/then on - sometimes works

It is not a trivial suggestion, this is part of the general troubleshooting steps to rule out hardware or software issues, if a forced restart does not solve the problem.

this is the last thing to do to be honest. giving such tips is simply ignoring that something is buggy, because it is...otherwise, you can close this community and write: do a full wipe and setup from scratch :)

If "something is buggy" I would call that a software issue and it can be reported it directly to Apple by using the Feedback link, this is the only way to make them aware of such things.

It may even be caused by a developer, if you are using 3rd party apps, for example.

Feedback - Apple Watch - Apple

This is a user to user community and Apple does not follow these discussions.
