All help or advice would be appreciated. I even re-installed Photoshop CC 2018 (windows) to try and see if it was a glitch.
I am creating simple motion animations using the 3D mesh presets like square, soda and hat. The results are good and I can export to mp4 without a problem but all my keyframes are lost when and if I ever reopen the file.
Also, simply clicking the keyframe on the layer does not resolve the issue for me as I have read as a possible fix.
