Jeremy, is this still an issue? I think the problem was that you had two transitions targeting the same View for the same action (e.g. two Slide() transitions).

I have a similar issue with plain AnimatorSet:
set.start()
set.pause()
set.setCurrentPlayTime(100)
set.setCurrentPlayTime(0)
set.setCurrentPlayTime(100)
set.resume()
doesn't play animation in resume().

Should clarify that if I filter out setCurrentPlayTime(0) (or replace it with setCurrentPlayTime(1)) it works well.
Also even with setCurrentPlayTime(0), onAnimationEnd is notified with correct delay (as if the animation has played).

Did some investigation on the Fragment side and it seems like the merged transition is targeting correctly.

Adding more debug logging in transitions to track the entering and

Description
STEPS TO REPRODUCE
1. Set up a Kotlin Activity that
a. Uses a ViewModel with the SavedState library
b. Declares the ViewModel with by viewModels()
c. Doesn't touch the ViewModel
2. Start another Activity using startActivityForResult()
3. In the onActivityResult() method, touch the viewModel

WORKAROUND
Touch the ViewModel before starting the other Activity, e.g. vm.getApplicationContext() is sufficient
