Survey123 Connect Proxy Service - Item does not exist or is inaccessible in Survey123 Web

[ShariForbes]

To create our survey to edit data directly to a feature class in our geodatabae, we have been following the steps How To: Create Survey123 for ArcGIS surveys that connect to non-federated ArcGIS Server services

I recently updated to SurveyConnect 3.11. After publishing the survey in Survey123 Connect, when I open the survey in the Survey123 web application to change some of the settings under "Collaborate" tab we get an error: Item does not exist or is inaccessible. 

I'm at a loss of how to fix this. I've added the xls form below. 

This is our survey https://survey123.arcgis.com/share/553079f5b265483083910f9f0e11da45
