Geo-location map doesn't update

Assuming the second case, the satellite imagery is not real-time (the map does not show what the satellites see when they fly over us). The imagery is from map providers who license and update it from imagery providers. SketchUp has no influence on that.

It is also helpful if you click the layers button (on the right) and switch to “Trimble Map” (MapBox/OpenStreetMap). It’s not a satellite photo, but in many locations OpenStreetMap is very up-to-date, e.g. if the online community maps buildings still under construction.

If you have more up-to-date imagery (e.g. screenshots from online maps, or friends that have a plane), you can import it and align it to the correct location.
See here for aligning an imported image, and here for projecting it on terrain.
