Garmin Connect website not syncing with Garmin Connect mobile

Former Member

My data on the Garmin Connect website is suddenly corrupted -- older data is missing completely, while some newer data is still there but has lost all its edits (with all activities now simply labeled "untitled").

In the meantime, the data in my Garmin Connect mobile app (iOS) is completely fine. It goes back as long as I've been using Garmin devices, and updates from my FR235 without any issues.

Even if the website lost data, wouldn't the data on the mobile app re-sync and update it? I'm signed in identically on both.

Advice? I don't want to risk losing all the correct data on my phone, but I use the website version for any actual analysis of the data. Thanks!

    Hi, I appear to have a similar issue but the other way around.

    I had an error message about a month ago where my Vivoactive HR would not update due to 'lack of storage', after Garmin tech support were unable to help I uninstalled and re-installed the app. After doing so I also cleared data from my phone, one or both of these has caused my Connect mobile app calendar to restart as of 12th April, restarting also all my records and badges. Unfortunately I have lost all data back to Christmas 2016.

    It is all still visible on the website. does anyone know if it is possible to resync the Connect app calendar from the web version?

    Are you sure you didn't inadvertently create a different account after you reinstalled Garmin Connect Mobile, with which you're now signed in inside the app?
  • Hi.

    Cheers for the idea, that was the first thing I checked, everything on that side matches up. It is good to see everything on the web dates back fully, just annoying that my device and Android phone only 'remember' details back to the 12th April.

    Anyone from Garmin care to comment on this?  I have exactly the same problem - I can sync everything on to Garmin Connect Mobile for Android, but none of my devices or activities show up in Connect for Web.  I am reluctant to do anything to drastic to Garmin Connect Mobile as I do not want to lose all my data. 

    Any suggestions? 

  • I am wondering the same thing! It's also been about 3 days. I updated my app, but nothing has synced to the website. Disappointed

  • 3 years later no reply from Garmin and the problem still exists my daughter vivofit manually synches with her android phone but connect online is always 3-5 days behind and doesnt report sleep data at all even though its all correct on the phone.

    pathetic - will be looking at other brands when this device wears out . Last weeks data is not useful.

    I have the same problem. The mobile app won't sync with the site. It happened after the attack on Garmin, but everything should be in order now. Well, it is not! My Fenix 5 connects with the mobile app, but the app won't show any of the gear, apart from a bike. Meanwhile, the site won't show any new activity, but it has all the gear and history. I don't have two different logins and I can't understand why does this happen and if it will be fixed. I wouldn't expect an answer from Garmin. Their customer relations department is known for not giving a s**t.

  • everything should be in order now

    That is correct. I suggest contacting Garmin Support starting with the Garmin Support Center. Phone or chat for the fastest response if possible in your location.

  • I don't have two different logins

    Despite what you tell, you very likely do have two different accounts. You can verify it yourself. On the phone app, go to Menu » Settings » App Diagnostics and note the Displayname code. Then open the web interface, click your avatar in the upper right corner, and select the option View Profile. Now compare the ending code in the address line of the browser, with the code from the phone app. If they are not absolutely identical, you have two differrent accounts, and need to use the same one on both sides. You can log out of the web account, and log in back using the identification from the phone app.

    Another possibility is to follow the instructions from this support document
