This series is cancelled. Does this mean it's status stays as "Returning Series" or can be changed to "Cancelled".
It should yes, but the TMDb Bot will come around every night and change the status back since there's episodes added that are set to air in the future. I still need to tweak the query the bot uses to ignore series set to cancelled and/or statuses that are locked. My ticket for this is here.
Since it was never available on a real streaming service, did it really exist in the first place?
