Photoshop Timeline Animation, Keyframes do not save

[cwvickery]

Is anyone else having an issue with animations in photshop timeline? 

I have created a 3D object, animated it using keyframes within the timeline (not using panels, but acutally using the timeline) - And when I save the document after working on my animation - I open the file back up only to find that my hard work (keyframes and the various changes I made to the object) have not saved.  Specifically Keyframes for the 3D meshes. Ver. 21.1.1

Cheers!

If I open a PSD that I saved a video animation where I animated  3D objects this is what I see in the Video time line and the animation plays. If your animation plays the the key frames should be in the animation with all the other frames.

If I click one the object clocks in this case earth and clouds I can see where the key frames are in their time lines.
