In Version 26.2.2 (Build 3) ,

previously i have the special Bezier curve in transform effect that visible in Program panel , after updated new version , i see many bug others not affect me , but the transform special brazier curve more important  for animation stuff , 

previously it show the keyframe dot  and the frame wise path how it animated ,  but now it show nothing that mean i unable to control the animation path in transform effect 

its core feature many editor used so as soon as possible fix this issue
