Pixel Watch 1 - Tracking & Sync still broken

[Ray519]

basically starting with the 15.08. the Watch stopped tracking & syncing most stuff. Since then there have been like 2 updates for the Fitbit Wear and Health Services apps, but its still broken.

What is broken:

The Fitbit App can access the current heart rate and it shows this in the Wear App, the tile and the complications in real time. The tile even shows the history as usual.

But in the Wear app, the Heart Rate page shows no history & details (normally the diagram shows more details about the current day and the heart rate range. both remain empty as if the watch has not been worn). Which is exactly how it shows up in the synced phone app.

Hitting sync on the Watch or in the Phone App seems to complete as normal, but nothing changes.

So my understanding of this is:

The Wear Watch has access to the data and stores it locally. Then there should be some post processing which the app should be doing to display all the data and count zone- and activity minutes that just does not happen / fails silently. And as a result, the post processed data that would be synced to the phone and uploaded is just missing.

The only thing still syncing to the phone is steps and trainings started manually on the watch. But the trainings remain completely empty, only showing time. On the watch, with an ongoing training, it shows the current heart rate, but the zone minutes just permanently remain at 0 as well. A feature that I also believe should be working even with the watch offline.

=> the Wear App is severely broken and fails to show error messages for where it fails.

I have now factory reset the watch twice and it did not change anything. Tried rolling back app versions and try different combinations.

I managed to fix it myself once by rolling back both Fitbit Wear and Health Services to the factory versions (factory as of BW1A.250605.004 the current firmware). Worked for 10min. But when I tried to update to current versions it broke again.

(a few days later) Then last Thursday (21st), the Health Services app got an update that fixed it and it worked up until sleep tracking (in the morning nothing worked again without me changing anything. Also it seemed not to have tracked stories walked up in the meantime).

For reference, why I even tried rolling back Health Services and the Fitbit Wear app: I have seen this (live heart rate but no actual storing, analyzing and syncing of it) once before. A while back when I was stupid enough to manually install a Health Services update while a had a training manually running. The tracking broke when the update installed. That was able to be fixed by simply killing the app, restarting and deleting caches. I lost all the between the update install and reset, but it worked again for anything else. With the exact same behavior, just without me triggering it, I thought the chances are high that the issue would be between the same 2 apps as before.

Any further suggestions for troubleshooting and investigating the reason for this failure to get it actually fixed?

Hi, @Ray519 , welcome to the community. Can you please let us know which cellphone you are using and its OS? Fitbit setup requirements - Help explain some of the issues. It sounds as if you have a syncing problem. You may find these articles of interest Why won't my Fitbit device sync? - Android - Fitbit Help Center & How do Fitbit devices sync their data? - Fitbit Help Center . 

Please let us know how you get on by posting here again.

Aaand, after the watch was off for the night, it fixed itself this morning. Again. Lets see how long this lasts now...

It was a Pixel 6 on Android 16, now its a Pixel 10 Pro on Android 16. Same issue after moving and reenabling sync with the new phone.

And the issues seemingly were never with the sync with the phone, but already on the Android Wear Fitbit app running on the watch.

Here an example to illustrate:

The watch app can see the heartrate, it knows how many minutes the heartrate has been in that zone, but it fails to accrue any "zone-minutes", which normally works in realtime (should just be the sum of all times in zones multiplied by some factor based on the each zone). And that specific function should be working even if the watch is offline and no phone is available, should it not?

Also here: the Wear Tile (home screen widget) shows the heartrate just fine and the history throughout the day.

But clicking that opens up the full app and its heartrate page, which remains empty except for the current live heart rate. The empty space should show a bar graph of the heart rate throughout the day based on the same data as shown in the tile, which the app obviously has access to. It also should show the range of heart rate (min. max.) of the day. Also not showing this.

Whatever does not sync over to the phone also was never shown in the Wear app to begin with. And whatever error happens, it should be happening on the watch, as it at the same time has all the data, but only shows it in some places...

It has now fixed itself without any visible app update (after being shut off for a few hours, which I have done lots of times before in trying to troubleshoot this). Lets hope this time it continues to work and does not break again all by itself within the day.
