Apple Watch GPS only tracking half an activity

I've noticed a bug with my Apple Watch GPS tracking over the past couple of months. Initially I thought it was just when tracking walking but I had the same problem with a run yesterday.

I would track an outdoor activity, and when I finished it the distance recorded would be complete but the map would only show about half of the activity. And when I would import the activity into Strava it would only detect the distance that was shown on the GPS track, not the distance that the Activity app was showing that it recorded.

Initially I thought it was just flaking out halfway through the activity, but yesterday on my run, I noticed that it happened at the point in my run where I ran down the wrong street and had to double back on myself. I then realized that that was a similar pattern on all the other activities that had the issue. It wasn't that it was 50% of the way through the activity, it was that it was at the point that I turned around and went straight back in the direction that I just came from.

Has anyone else had this issue?
