It was an issue a year ago and now again since about 2 months, my IQ watchfaces occasionally place my sunset time to late for my location.
And the location on my watch is off by about 400km in another city (and that's not the city that belongs to that sunset time).
Depending on how often the watch face updates itself it can be immediately corrected by accessing a widget that's requesting a location from the phone or doing a GPS time sync.
It's most unstable when moving about in the city, almost reliable if I stay in the same place all day. Happening on Android if that plays a role as the phone is responsible for updating my location, maybe a problem with location if there is no known wi-fi? IP location could just be from very far?
Worth noting: the wrong sunset location must be on the other half of the planet, as the day there gets shorter while for me in the correct location it gets longer.
The wrong location seems to be always the same.
It's two situations:
1: all good, watch knows where it actually is and sun times are correct (1st location)
2: all messed up, watch thinks I'm 400km away from where I actually am (2nd location), sun times are in an even different place more that 400km away (3rd location)
Thats hapening on my Fenix 7, 6 and today I will also get the F5 out to test.
