Problem with location accuracy - by around 100 miles!

Just wondering if this is a known bug at all?
Location seems to be very inaccurate when using browser geolocation.

Happens in Google Maps, netweather.tv and any other site granted location access.

It seems to put me around 100 miles away in Huddersfield but the problem doesn’t happen in Chrome which seems pretty accurate.

I’m running Linux Mint 20.1 and Brave version 1.19.92 Chromium: 88.0.4324.152 (Official Build) (64-bit)

Problem occurs whether shields are up or down.
Testing Brave on my Android phone (on the same wifi at home) it geolocates accurately.

Is there any work around at all or is this an actual bug in the system?

Just seeing if I can bump this up for any response or is this community just for BAT and revenue problems (which at first glance it looks like!).
