Map lost after workout

[rbart]

Hello all.
Yesterday I ran a race with my Aw5 LTE and apple stock workout app.
My watch and my iPhone 7 are up to date and after the race, I have discovered that the map has not been transferred. I only have one point in the center of the map.
Usually, it works without issue.
3 weeks ago, my wife had the same isssue with her aw3 and iPhone se.
Did you have the same problem ?
Any solution ?

I get this from time to time. Probably twice a year or so. I’m not sure what causes it or how to fix it.

Had this some time ago. Rebooted phone and watch and map was there.

It didn’t work. The map was here but corrupted...
