My customers and I are experiencing issues where the messenger cannot be hidden after it is opened. Clicking the messenger button in the bottom right corner just opens another instance on top of the existing one. When the new instance is opened on top of the old one the collapse arrow appears over top the messenger. Clicking the collapse arrow closes the second instance but there is no way to close the first instance of the Messenger. There is no X or collapse button. It is functional, just cannot be closed.
