This app uses the URL search param to select & zoom to a specific route based on the ID number. The end of the URLs below show this as "&ID=6673" for example. If you take that off, the app will zoom correctly to the default extent.
When I enter these URLs now, it zooms to some far away place, not to the specific location. Did an update to AGO change this behavior? I checked the app configuration and all looks good in there.
