[BUG] SW23.20 - altimeter not recording/erasing history

Hi!

Today i found a new bug for me, this time altimeter!

Widget is not recording any altitude and probably also its deleting history from it.

Photos from elevation glance:

Today (Saturday) - recording started after ending of activity.

Friday evening (time when GPS was active and activity was recorded) - history is gone

Also - when I checked my today activity (running - 2 laps on the same course) First half (lap 1) of elevation profile is OK, but another half (lap 2) is some kind of inconsistent, full of ups/downs. Second lap should be identical to first one, smooth without any major bumps.

Sorry for blurry image - I don't know what is happening.

Anyone having similar issues?
