Research direction
The issue reports slow expansion when a group has 8-12 children views. Start by reproducing the issue with a minimal example using the library. Check the group expansion logic in the library's source code, particularly any animations or data updates. Look for comments in the issue for any suggested fixes or maintainer responses. Consider profiling the layout pass or investigating if notifyDataSetChanged is called unnecessarily.
