Apologies for the issue and the experience that you described above. I have an inquiry now in with our On Demand content team to see what's up and so that we can get this episode available. Thanks for your patience.
peb7 -- The content holder has not guaranteed us the full season of Season 4. Episodes 9 and 10 are the only episodes we have been provided.
