Troubleshooting guide for (some) data missing after syncing

When you find that after syncing, part of the data is still missing in your Garmin Connect Account (for example the heart rate, steps, Intensity Minutes, or Activities), then there are basically the following possibilities. The most common and the most likely reason in most cases is the #3, despite that people are always persuaded they never created multiple accounts. Unfortunately it happens far too easily to tap the more prominent button Sign Up instead of Sign In, for example when reinstalling or restarting the GCM app.

  1. Your Privacy Settings do not allow sending data to the Garmin Account (verify the option Storage & Processing), or the device is not set as the Preferred Activity Tracker (check out the Device Settings on the Garmin Connect Mobile app » Activity Tracking » Preferred Activity Tracker)

  2. The BT synchronization on the phone app does not work (the white circle around the watch symbol never closes) - in that case follow the tips in the Sync / Connection Troubleshooting Guide. Alternatively, you can sync the data with the GC account over the USB cable and Garmin Express on a computer, or manually by importing files from the device folder //GARMIN/ACTIVTY/ to the Import Data page of GC Web (in case of errors during the import, see the hint #4). On Android devices you can (and you should) also review the Device Sync Audit (in GCM Menu » Settings), and browse though the last audit reports looking for errors and warnings.

  3. When the synchronization works (the white sync circle closes and turns green), but not all the data is appearing in your account, then it very probably means that your device is associated with multiple accounts, and a part of the data lands in the other account. It frequently happens for example when you reinstall the application, and inadvertently sign up a new account instead of signing into the original one. Follow carefully and in the described order all the instructions from the support document Data is Missing from My Garmin Account After Syncing to resolve the issue. When it does not help, perform the Master Reset of the watch/device - it will have similar effect, but you will need to redo some configuration and customization of the device.

  4. The storage (or a FIT file storing the Activity details or HR data and the steps data) is damaged or full. Try backing up and deleting old files from the folder //GARMIN/Activity and //GARMIN/Monitor. Look up the last unsynced activities from the folder //GARMIN/Activity, and try importing them manually on the Import Data page of GC Web. If you get errors when trying to import them, try fixing the broken files by passing them through the Section Remover of FIT File Tools (without removing anything), and then importing again the repaired file(s).

  • Some addtional info to the hint #3:

    You can check whether you are concerned by the duplicate account issue by looking up your user name, and your email address(es) on the Connection Search page. Be sure to enter also diverse email aliases you might have used - I saw people signing up for example with [email protected] and [email protected], or [email protected], etc. If the searches show more than one hit for the email address(es) or screen name, you found the culprit.

    You really have to follow all the instructions, and in the right order. You have to first remove the device from the Garmin Connect Mobile app, from Garmin Connect Web, and from Garmin Express. Then sign out of all three apps. Restart the watch. Now sign in back to all three apps with the very same credentials, and the device there. You do not need to reinstall the apps.

    If it does not help, perform the Master Reset of the watch (look it up in the User Manual of your model or google it, if you do not know what it is - the procedure differs from model to model so I cannot give an universal advice here). Just note, that the Master Reset will wipe most of the settings and customizations of the device, and you'll have to redo them.
