Hi, there!

There is no add button in the aftereffect software. Does anyone know why?

Thank you!

Try clicking the icons on the lower left hand corner and see if it appears.

You need to have the Switches or Modes column active. You can do that by clicking the second icon at the bottom right of the timeline or by right-clicking anywhere in the Column row at the top of the timeline and turning the column back on.
