This is present on xbox as well. I noticed it had become stuck on a proceed aspect after it caused me to spad, I was going to submit a ticket but never got round to it.
Same here. The repeater doesn't update. Watched a train leave platform 7 and its status doesn't change despite the signal ahead changing to danger. Thank the 377 for the time being has very responsive brakes if you were relying on this and no HUD signal.
