History Data Not Logging

Restart watch and phone. Restart watch by holding the light button for a long time until the watch restarts. It might be a different button on your watch.

Connect watch to Garmin Express and check for updates.

Thanks, but I've tried restarting both (fenix 5 and phone).  It syncs activities ok (including all telemetry) and shows the current day's data (as per screenshot), but simply isn't saving the data into the history.  I pretty sure this isn't device related, but perhaps I'll try syncing with a different device to be sure.

Have you checked the settings for activity tracking? The missing functions are only the activity tracking data.

Yep.  Activity tracking is on.   It's pretty odd.  It simply stopped saving the history on the 19th of May..... everything is there before that..... I've had no device changes.

Turn activity tracking off, sync, turn it on, sync.

Interesting development.  I installed Garmin Express on my laptop (Windows), connected with USB cord, did all the sign-in stuff and now it's showing all the missing data from May 19 on.....

Hi Garmin Support team! I also experiencing data not recorder since the last firmware update on May 18, 2023. Could someone from your team contact me and guide what to do next when all the instruction didn't work. Thank you

Can someone from Garmin support, explain to  me why my data still not recorded on Connect mobile for more than a week now.?  I followed all the instruction but still nothing happens.

What instructions have you followed? 

Garmin Express is usually the way to solve sync issues.
