We appreciate your first post here in the Roku Community, TheFutureFlash7!
We'd be happy to be of assistance here and provide further information regarding the availability of The Nanny series streaming on The Roku Channel.
As of now, I would like to inform you that the only seasons currently available in this series are Seasons 4, 5, and 6. Rest assured that I will coordinate this with the team for further information about the availability of the first 3 Seasons.
I'll let you know once more information is available.
Thank you for your patience and understanding.
Warm regards,
Carly
