Enduro 3 restarts when trying to save 16h activity

Hello,

Last month I purchased an brand new Enduro 3. While training for an ultra I did record several hundreds km of trail running with it. All worked fine. I had the longest run about 8h. On the 7th Dec i had my ultra: Chiang Mai by UTMB 100k race. I finished in 16h. When on the finish line I saved the activity. After looking at my watch a few minutes later I saw that the "play" icon was on the screen as it is when starting. It started and took me directly to the stop activity screen where I could hit "save" again. I did save again and this time it worked. The activity also did not sync afterwards with garmin connect ( and thus not with strava ). I had to manually copy the activity file from the watch itself to my computer. I tried first to upload the activity file to garmin connect ( on the web from my laptop ) and that did not work saying that the activity already exists ( allthough it does not show up in GC or strava ). I uploaded the activity file on Strava and it worked  flawlessly. 

I assume that this bug happens when the activity is longer that a number of hours which is grater than 8.

So what's up with that Garmin ?? It's a 900 EURO watch targeted at ultra endurance with battery lasting a long time but the "save" does not work ?? I don't even want to think to the scenario in which it lost my activity altogether... but certainly now I cannot trust it to record another ultra race with it. I realize(hope) this is a software bug, when will this get fixed ?

I had the latest firmware 12.22 when this happened.

    Over the past 3 weeks this has been a fairly common issue with all the fit file repair requests I see. Basically, the fit file somehow is partially uploaded but doesn't display in Garmin Connect. After attempting to repair it and upload again, you'll get the "this file has already been uploaded" error message.

    There is 25 MB limit - File Size Limitation of Manual Uploads to Garmin Connect

    If that is the issue, there is specific software than can reduce the number of trackpoints to allow it to upload successfully. 

    Feel free to zip and attach the file here or you can Private Message me.

    I did the test. I started an activity with the watch near the window to have GPS signal. I let it running for 16h. I saved and it worked. NO restart this time. I had  "Position Enhancement -> off" this time, at the race when the restart on save happened it was enabled. Maybe this was the culprit. Or maybe other factors come into play...

    I had an similar issue when I completed the Yorkshire 3 Peaks this week. I got the ‘blue triangle’ screen on 4 separate occasions followed by a reboot each time. This was extremely frustrating as I was the navigator and timekeeper for the challenge. Luckily the watch resumed the activity each time, but unfortunately I did lose some tracking distance and came up a mile shorter than my team mate who had a Fenix 7X.

    On completion of the challenge, the watch got caught in an endless loop trying to save. I later discovered that the activity was not uploaded to Garmin Connect but did save down to the watch. After numerous attempts to synch the activity using Garmin Express - including a manual upload (which returned an error) - I was able to use a FIT file viewer to fix the corrupt FIT file and then manually upload to Garmin Connect.

    This issue has also happened to me before on another long hike so it looks like it is a serious bug for longer GPS activity types. For reference I was using the latest 15.32 firmware and had the display on maps.

    Please fix this Garmin!
