Problem persists in Windows 11 version 24H2
I just installed the latest 24H2 update for Windows 11 last week. Unfortunately, the "Expand to open folder" issue is still there in Explorer. If the updates are not resolving this issue for users, then I suspect this issue can only be a bug. This feature failed to work on day one after receiving my new computer.
A search on the internet is not revealing any solution to this widespread problem.
The only way to move forward is for thousands of users to report this issue through Microsoft's feedback app. I suggest including a short video demonstrating how the Expand to Open Folder feature fails to work. Describe the problem. And check the box asking Microsoft to contact you.
