Firemonkey TMemo OnChangeTracking strange behavior on Android


Does any one had same issue, then on run time created TMemo fires OnChangeTracking only then TMemo is empty (no lines) and only for the first entered symbol. And also then all text is deleted?

If TMemo is created in design time it works as it should.
This behavior is only on Android. iOs and Winows is ok.
Is it a Delphi bug, or maybe there is something I can fix? I use Delphi 10.3 Update 1 at the moment, don’t know if problem ocurs on 10.3.3

Here goes a litle video:
