When you are in the middle of a session, and you update the app at the same time. The history of that session is lost. I experience this in the "Chats"

Start from the /chat path and reproduce the reported scenario on Windows 10: update the app while a session is active, then inspect whether its history remains available. Done means the session history is preserved across the update; the issue does not name files or tests to guide the implementation.
