I am not able to select anything but "Create Frame Animation" in the Timeline. I am trying to create a Video Timeline, but not using Frame animation. This option isn't in the bottom left or top right of the Timeline menu.
I have tried resetting my preferences, uninstalling and re-installing, creating a new document, and converting all layers to smart objects, and none of those have worked. I have a macbook pro with macOS Big Sur version 11.2.3 with an Apple M1 chip.
