Xbox Series X Still Can't Acknowledge Pzb Or Sifa With Salzburg-rosenheim 766.2 Cab Car Using Xbox Controller

On console - at least Xbox Series X - when driving the Salzburg-Rosenheim version of the 766.2 cab car you still can't acknowledge any safety systems - PZB or SIFA - with the 'B' button on the Xbox controller like normal. This is really frustrating to say the least because it's a key part of immersion for this game and, apart from this, the route is still one of my favourites overall.

So, after all the recent updates, I'm bitterly disappointed to see this outstanding issue has still never been fixed - I just don't understand why?

A question to those on Playstation, is this a wider console-specific issue i.e. can you acknowledge PZB/SIFA using a Playstation controller with the Salzburg-Rosenheim version of the 766.2 cab?
