Hi all. My Remote control app on 2017 AB has started an intermittent fault on the recording detail

of Journey Details. The text info ie duration, avg speed, distance etc works fine. It is however the display of the journey route which is working intermittently. As can be seen on the photo, it starts off recording the route ok, but after it while it just goes to a straight line between two points. Until recently it worked perfectly, but now I'm getting this straight line displayed on partial or sometimes on the whole route.
I have reinstalled the app. several times but this makes no difference.
kind regards to all P current 2015 hse dynamic, grey.
