We are aware of this issue, and while it has been resolved for most users, a small number may still experience it.
Our engineers are actively working on this problem, but a permanent solution is not yet available. In the meantime, the only known workaround is to shut down the hub from the Settings menu, then unplug it for 1 minute before plugging it back in. While we understand this is not an ideal solution, please be assured that a permanent fix is in development, though we are not sure at this time when development might be completed.
