Doc or code issue: use GPS for location 

The description says:

>  NEW: now you can get location directly from GPS on your watch. With the app open, press MENU button and choose "Get location from GPS".

This doesn't appear on my FR255.  Version 15 (the later one, 12 Dec).

I've got a valid OWM API key, have sunset time and have just gotten a GPS fix, and still get the message:

> GPS or API key?
