The mirror answered "dashboard" for a browser that had simply never been told, and RootRedirect took that as the user's choice - so the setting was ignored on every device except the one that set it, and on that one too after a logout cleared the mirror. The setting itself was stored correctly the whole time, which is what made it look like nothing happened. readStartDestination now says "unknown" rather than guessing, and a device in that state waits for the real settings instead. That costs one wait, once per device; afterwards the mirror answers and the launch is as fast as before. Bounded by a timeout, because loadSettings deliberately leaves isLoaded false on a failed request so it can retry - without the floor, a launch with no backend would sit on the spinner forever.
