Since about a week ago, the driving mode button by the gear stick no longer brings up the choices on the infotainment screen with a press. Driving mode can still be changed by double-pressing the button and cycling through the options. I presume some software update is to blame - I have noticed at the same time that the name of the road the car is on is now displayed in the top-left of the screen, which did not used to be the case.

Anyone else had this?

Vaguely remember someone mentioned mode button is affected by leaving either speed limiter or cruise control on, turning it off sorted problem.  Sounded like software glitch

It's not the speed limiter or cruise control in my case; they are both definitely off and I tried switching them on and off just in case, to no effect. It must be some software glitch as you say as I'm sure it started happening when the current street the car is on started to appear in the top left on the infotainment screen.
