Very strange issue with S6 GPS

[Swordfish]

My S6 did a software upgrade yesterday and now the GPS is telling me that I'm at the ASDA Superstore in Mansfield.

No matter what I do, it refuses to correct my location and I am actually 334 miles north of this in Dundee.

Anyone else having issues like this.

Android version 6.0.1

TIA

Appears to have sorted it. Had to reset GPS data with GPSTest from Market.
