My Vivoactive 6 is not syncing my activities in Mynetdiary

4635372 3 days ago

Yesterday (11/17/25) my Vivoactive 6 stopped syncing any activity (steps) and resultant calories to Mynetdiary. I've done all the troubleshooting including restarts of all devices, unpairing and re-pairing, uninstalling and re-installing apps. Seems to have stopped suddenly and I'm not sure how to fix it from here. Is this a known issue?

I saw a Reddit thread from a few days ago titled “Garmin not Syncing” on r/mynetdiary. From what I read, it seems that MyNetDiary support is currently working on a fix.

It's happening to me too. Last update was 2025-11-17 17:23 UTC, then nothing since. I'm not sure which end is broken, since both services are otherwise working.

I would try to toggle off/on from both sides.

In MyNetDiary - unlink Garmin
In Garmin Connect app. More > Settings > Connected Apps > MyNetDiary > Disconnect. Close the app.
Then from MyNetDiary - link Garmin
Check in Garmin Connect that it is enabled again.

That's very unlikely to work when it broke for everyone on the same day.
And somebody who tried that in the iOS app reported that it was impossible to add it back.
