@Suty hiya. It was set to GPS but that wasn't working so set it to my home location and that also isn't working. See screenshot of my settings and what I get when I load Windy... Inchlaggen is north Scotland and a very long way from me!

(I can't seem to attach a screenshot, sorry!)

I visited a place 300miles from my home a few weeks back, now everytime I load Windy it defaults to this place. It is not a favourite. I have checked all my settings and it is not in anywhere and Windy refuses to default to my starred location.
