We have a public facing Instant App using the Zone Lookup tool template that appears to have been broken with the February 2024 ArcGIS Online upgrade. The map is still appearing correctly, but in the app it does not show the map at all...

The app is here...
DBI Credit Program Subdistricts lookup tool - Overview (arcgis.com)
The map the app uses is here...
DBI Credit Program Sub-districts (arcgis.com)
I tried selecting the map in the app again, but that didn't fix.
Please help us fix this!
