GPS not tracking full workout

Just today I noticed that the past few workouts I tracked with GPS are not showing the full workout on the map.

The correct distance shows in the stats, but the map appears only to show the second half of the workout. This happened to both bike rides I did today. In fact, the morning bike ride appeared in full shortly after I completed it, but now it's only showing the second half.

AND, previous workouts from last week now only show half on the map. They showed the full route until I checked them today.

What is going on?

I've noticed this as well, past tracks are also shortened to just the last part.  I noticed sometimes that the entire track shows for a brief moment, and then most of the track disappears.  Also, now the cardio load for my past activities all show zero, the daily cardio load is still calculated, but the app says that it all comes from general activity and not from logged workouts.

I hope that this isn't Google trying to save money by limiting storage!
