I see -- then definitely try the ArcGIS Online questions board. I would think someone there can help get your questions answered.
Also, can I ask why you are using a feature service for your tour? That workflow is primarily designed for situations where you have an existing feature service of data created via another ArcGIS app like Field Maps, Survey123, or QuickCapture. Is there a reason you aren't building your tour in the story builder?
