Route no longer recalculating as I drive?

The route has stopped recalculating if I deviate from it. If I don’t follow the route it clears to no route.

I have looked through settings and can’t see if I have turned something off. It is still set to use live data.

I am on the latest app version, latest IOS, and using Apple CarPlay in an ID3 on 3.7 software.

Can anyone advise? The app is useless if it doesn’t recalculate.
