255s user here, living in Norway, southern Troms.
Usually absolutely no problems with the sunrise widget (*no* GPS/location problems!). I get lots of use out of it.
Polar night just started for me. First time for me with a Garmin watch. The sunrise widget is telling me that the next sunrise in 596533 hours - or about 68 years.
I hope this is a bug and I didn't miss any big news.
When this gets fixed I would also appreciate a change in time format:
If the next sunrise/sunset is in more than, say, 48h, give the duration in days.
Thanks from the beyond the polar circles!
