I just came across this topic that seems to have been unresolved. I see the same thing posted by OP. It only affects aircraft that are close and EFB starts to show the live aircraft. However, rather than replace the red icon, it adds a blue and the red and blue aircraft icons are both shown with the red icon trailing the blue. It looks like two separate aircraft and is pretty distracting. Is there any way to merge the two?
