Segments – not showing me in leaderboard, not showing in activities

A few days ago I have noticed that segments stopped working for my person.

  1. My name disappeared from leaderboards of all segments where it had been all along (for some years).
  2. In activity view the "Segments" section header is no more displaying under all graphs of activity - in the line with "Stats, Laps…" even if I certainly know that I cycled through existing segments. See image. Same behavior for all my activities, i.e. also for older ones, not only recent.
  3.  I also can not see my name in segments leaderboards in mobile application.

All seems to me as if my name was completely removed from Segments feature. Is any reason for it? Am I missing something? Are Segments feature paid from some time, or what could happened?
