Elevation out of sync with location

On a ride last week I had a strange problem where the elevation was being shown for the wrong location, lagging behind where I actually was. it got progressively worse and by the end of the 100k ride was behind by about 500m. I was getting climbpro notifications of upcoming climbs, when I was already half way through them.

I've seen this once before, when I was doing the Dragon ride a few years ago, and wonder if anyone else has seen it?

My 1040 is on the beta programme, but I confirmed that other people in the group using Garmin devices (530 etc) and not on the beta had the same issue.

The ride was created on Strava and automatically transferred to Garmin Connect. As far as I can tell the route itself looks OK, and I create all my rides this way. I have 200+ routes created in my Strava account and use different ones weekly.

Looks similar to this issue

There used to be an issue in the route transfer interface between Strava and Garmin, where the elevation data was completely messed up, could this be related?

    I did another 100k route today, the Hell of the Ashdown. I had the same issue, where by the end of the ride the elevation track was way out of sync with the location. On the final big climb, Brasted Hill, when I'd finished it, my garmin elevation page, climb pro and the elevation trace at the bottom of the map page all showed my location as at the bottom of the climb.

    Here's the segment on veloviewer as far as the turn off on to The Nower

    And here's what I see on my 1040 at the top. I've finished the climb but it shows me at the bottom.

    Heres climbpro just before the turnoff.

    Its completely wrong, and matches what I saw on the rest of the ride. The elevation page showed me going up when I was going down, and down when I was going up. Heres another screenshot of when I'd just finished the descent off Brasted down Hogtrough Hill. I'd already finished the descent but it shows me way back  https://veloviewer.com/segments/7344252

    I'm having the same issue. Did you ever get it sorted?

    I'm having the same problem with my 1040.  The elevation profile shown with the map and on climbs is almost always completely wrong.  On climbs, the elevation remaining sometimes will just get stuck and the graph will simply stop updating.  Both the map profile and the climb profile are completely unreliable.  Often the the graph will show that I still have climbing to do but I'm at the top of hill... Or I will show that I'm at the bottom of the hill. I'm actually in the middle of the hill etc. 

    I wonder if there's something wrong with the altimeter in my unit. It seems to consistently overstate the altitude gained compared to other people's devices.  I hope it's not a hardware problem but I'm surprised that there aren't lots of other people reporting the same issue.

    I still have the same problem with Garmin 1040 solar. Most rides where good and accurate, after Garmin told me a few weeks etaleur to make routes in Strava actualy and than ride it. Not to use a route that was allready made. But today I ride a route wich I made yesterday in Strava and again there was a difference between the real route and the hill. About 250m.
