so, if the app was coded perfectly, and the last known good position was 
5 hours old and miles away, it would give the app the last known 
position, and the app would then decide it is too old, subscribe for 
updates and wait for a fix. That is the absolute best an app or web page 
can do if the platform is working as designed, make the human wait, or 
use a bad location. The app can't be written better because getting the 
first fix needs to be pushed back in time to shortly before the app starts.
Incidentally giving a rubbish first fix also often means downloading a 
page full of completely the wrong map tiles, which means more making the 
human wait.
