Missing data in Garmin Connect (Web & Mobile)

Following...  I have the same issue. Widgets will show the data but it won't sync to Garmin Connect.

There are several possibilities (listed below). The most common and the most likely reason in most cases is the #3, despite that people are always mistakenly persuaded they never created multiple accounts. And in your case the lookup for your user name reveals several Garmin Connect accounts using the same name, so the probabilty that you have more than one acount is rather high, too, I'd tell.

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 Garmn Connect Mobile app » Activity Tracking » Preferred Activity Tracker)
   
   
2. The BT synchronisation 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 compuiter, 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 #3)
   
   

3. When the synchronisation 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 all the instructions from the support document Data is Missing from My Garmin Account After Syncing to resolve the issue.
   
   

4. The storage (or a FIT file storing the Activity details or HR data and the steps data) is dammaged 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).

Believe me, it is almost certanly caused by a duplicate account. I saw hundreds of similar cases here on the forum, and practically every single user compaining about these symptoms swore he did not have any duplicate accounts, but in fact they all had.

Try removing your device from Garmin Connect Mobile, from Garmin Connect Web, and from Garmin Express. Sign out of them all, then sign back with the same credentials for all of them, and add your watch back.

You can also perform the master reset of the watch, if you prefer - it has similar effect, but additionally you'll need to redo some of the configuration of the watch.

all allowed and I have only one device which is set as preferred.

I'm sure that I have only one account which is used since buying my first watch (945 is the 3rd device)

I looked through the contents of the folders on my watch and when I tried to import manually files from the last few days in GC web I have message that they are already imported.

Follow the steps anyway. I do not remember anyone with exactly this issue who would not swear having only account
