I want to remove data that is shared to our open data portal. However, I cannot find how the data is shared to the Hub site in the first place. There are no corresponding map image layers, feature layers, or feature services shared to the AGO Group that controls content displayed in the site. Indeed, none of the layers are even in our AGOL as far as I can tell. How do I unshare an item that isn't visibly shared in the first place, nor even existing inside our AGOL portal?
Ghosts in the machine!!
I went to our Open Data portal to get the URLs and they disappeared, I think as a result of unsharing an app that contained the map services to those items. We re-shared the app to see if they pop up again. Not sure how long that would take, though.
