Fitbit not exporting Laps in TCX to Strava or in app Export

[bengutierrez]

Summary

Fitbit is not exporting all the laps in the TCX file that I can export with my phone app. It also doesn't sync the laps to Strava.

I dug around in my Strava account: The last time I saw it working correctly was in June 2022 and it definitely wasn't working by January 2023.

Details

I exported the data from Strava (file named 18x_200m_Repeats.tcx) and from the app itself (fitbit_export.tcx).

The files are the same:

% md5 18x_200m_Repeats.tcx fitbit_export.tcx
MD5 (18x_200m_Repeats.tcx) = 32c64841a318e05597d65c958b5553e6
MD5 (fitbit_export.tcx) = 32c64841a318e05597d65c958b5553e6

Both files only contains one <Lap/> entry (date and time censored because it's not allowed?... the date is today's date):

% grep '<Lap ' 18x_200m_Repeats.tcx
            <Lap StartTime="20XX-XX-XXT11:19:14.0XX-XX:00">

 The app has tracked the individual laps correctly and is displaying them:

Phone: Google Pixel 7, Android 14, Build AP2A.240905.003

App Version: 4.28.3 (110133304)

Device: Sense, FW Version 44.128.6.17

Expected behavior

Each of the laps that Fitbit knows about should be exported in the TCX file that may be downloaded and in the data that is synced to Strava.
