I was updated to 6.10 while sleeping. This morning my weather wouldn't update (Garmin watch face or Garmin widget). Has anyone seen this issue after update to 6.10? It may be a coincidence but it was fine until update. Thanks!
The watch (and phone, I think) need to know where they are to get a weather update. Unfortunately your last known location gets overwritten as part of the update process. If you can save a GPS location/activity and sync it to GPS, you should be able to get a weather update after that.
