Yes, this always happens to me. I reported it here a few months ago and also during my dealer visits but they had no solution. I frequently get a quick message that disappears from the dash or have the fourth pane taken over with the messages icon but there are never any messages when I open the messages app. It's definitely a highly buggy or failed feature.The car displays a message stating new message saved, but nothing is shown in the car status menu.
Anybody experienced this? Happened after SW upgrade
