I used GPS on my Bangle.js 2 today for the first time. First fix happened sometime during a 20 minute bike ride (travelling at about 10mph) but I'm afraid I don't know how long it took. Subsequent fixes today have been very quick - something like 30 seconds.

I've still been unable to get a fix.
Has anyone managed to? If so how long did it take?
