Description

Description

Initially opened as an Expo bug but seems like a react native 0.76 bug.

Link to initial issue for context: https://github.com/expo/expo/issues/32868

When showing or hiding content, LayoutAnimation.configureNext(LayoutAnimation.Presets.easeInEaseOut); usually automatically applies the "next" animation (Like opening and closing an accordion).

With react-native 0.76 and the new Architecture, this does not work anymore.

Steps to reproduce

1- Start a new react native project (with or without expo)
2- Create an Accordion or Collapsible component like https://snack.expo.dev/@baltagih/b638ce
3- LayoutAnimation.configureNext() does not apply the animations

React Native Version

0.76.1

Affected Platforms

Runtime - Android, Runtime - iOS

Research direction

Start with the LayoutAnimation.configureNext() call in the linked Expo Snack and reproduce it in a new React Native 0.76.1 project using the new Architecture. Compare behavior on Android and iOS; done means the next layout change animates again instead of silently doing nothing.
