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).

I think that is intended for Animator. If you set the currentPlayTime to 0 or the total duration the animator completes. We do some

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

Add additional logging for transitions
Adding more debug logging in transitions to track the entering and
exiting transitions as well as the final merged transition and its
targets.
Test: added logging

Description
Version used: 28 (same on 1.0.0)
Devices/Android versions reproduced on: 8.0
If this is a bug in the library, we would appreciate if you could attach:
- Sample project to trigger the issue.
attached sample project:
on app start you can see animation on child fragment enter (slide down)
with pressing "back" you can see correct exit animation (slide up)
with pressing button on center of screen you can observe error -> fragment should disappear but enter animation is played
RCA: (as far as I investigated that)
971 -> here child FragmentManager try to load animation for fragment but fragment.getNextAnim() still return "last" animation which is enter -> it should be updated to exit animation before -> in this place fragment manager know that it's removing fragment
