Where is the Transform Track menu in Level Sequencer Editor in 4.20 ? Need help. :)

Is there a bug in 4.20 ver about Sequencer Editor?

I can’t found the Transform Track for some components.

in 4.19. it show the “Transform” here. but there is no “Transform” menu in 4.20

For 4.20, we disallow transform tracks for any components that have their mobility set to hidden (in this case spring arm). As a workaround, can you use a scene component instead and parent the spring arm to it? You should be able to add a transform track for the scene component.
