If you see GPS inside a data field, this means that the watchface does not know the GPS position yet. To solve this, you need to do following:

• get a GPS signal (open an app like running, wait for the green GPS signal and go back to the watchface)
• return to the watchface
• suntimes data will be shown immediately, weather should update immediately as well (attention: inside Phoenix V1 weather will need about 10mins until it’s updated after this)
