Some firmware versions ago a bug was introduced that the off segment notification usually comes twice. First when you've reached some distance from the segment start, seconds later comes a new segment approach note for the very same segment (even though you're driving in the opposite direction) and some more seconds later a final off segment notification. This bug got worse in firmware 20.19 because now the off segment notification uses not only a short beep as before but the long, sad "Your PR time has been reached but you're not at the end of the segment yet" sound. This is very annyoing especially if you ride in a group and everybody turns to you and asks what that was.
