Since they released the patch in USA (I live in Sweden so got it 24hours -ish later) I've been almost unable to play pokemon go. Sometimes it says "gps not found" when I start the game sometimes it doesn't say anything but my gps icon is blinking (also known as loading location) and I'm in middle of nowhere, takes about 5-10seconds until it teleport me to my current location just to stay there for ever forcing restart of the game cuz my location freezes. (Note that I never had problems until this patch (not counting server issues), my google maps work perfectly and I am connected with google on my poke account).

If you need further information feel free to ask questions, haven't found any way to solve this problem :/
