I'm linking couple artboards and for some of them I can use the "Push up"/"Push down" animation (using tap trigger, transition action) and for others, the animation options are disabled.
I noticed that when the artboards have differente sizes, the list gets disabled, but this is not the case: both artboards have the same size.
What variables can disabled the animation list?

Sorry for the trouble, and thank you for sharing the screenshots. Could you please share the screenshot of both the artboards individually showing dimensions as shown in the below screenshot?
For the screenshot 2 issue, you can increase the viewport height of the shorter artboard to the same size as the longer artboard to enable the Animation option.
Let us know if that helps.
