This question went unanswered last month, and the month before that, so I am asking a third time:

When will the Expedited Update feature be fixed?

I again share my Tech Community post: Did expediting the 2024-08 Quality Updates fail for anyone else? | Microsoft Community Hub. Every month since then I have been expediting the B release to a small test group, and each month we see the same issue: the computers aren't rebooted after the update installs; instead, the update is repeatedly installed and reverted for days on end until the computer eventually restarts (or is restarted by an end user).

My support case was closed in May after I was told that the product team had found and fixed the issue, but the issue wasn't actually fixed.
