Orphaned Content -- Application listed does not exist even after forced refresh

Question

I have an odd one folks that has had me pulling my hair out. My site is displaying content that no longer exists (and I have searched the entire org to verify).

* Go to https://data.bellevuewa.gov
* Search "multi-family" and hit enter
* Results will show an app named "Bellevue Permits Multi-Family, Apartment and Condo Projects"
* Click on the app...dead link.

To correct the issue, I deleted the original content, forced the content update (3-dots Check for Updates), I recreated a similar application and name, etc...etc. As it failed in all cases, a support ticket has been opened (see below).

Good morning @HenryLindemann,

I dug into this a bit more. The URL is trying to get to this itemID = 5b879b1edd9a478b9ddbc5cbf673d9cc, but it does not exist in ArcGIS Online.

From the hub address, no joy can be found. It does not even list.
