Blender 2.8 - Pose Mode undo error 04-06-19 to 06-06-19

Hi,

I found an error on the newest versions of blender. (from days 4 to 6 of this month)
If you create an armature and try to move it an then ctrl+z it doesnt undo.
If you move anything in pose mode and redo nothing happens.

version of today(07-06-19) still with the same problem
