@Delta2k5 Thanks for the response. I think I may have just been unlucky to randomly visit many of these places all at the same time, but will be doing some more testing over the next few days. Worst area seems to be 54.093424, -4.650603.
@Jord524 Hi, as I said above I’m now thinking it might be the satellite coverage in areas I’ve gone to (even though they were thousands of miles apart). I’ll be doing some more testing though. What are the coordinates of the area you see it in?
