Steven and I have managed to get the polygon layer working in the mobile app, and I wanted to share the steps we took to resolve the issue in the Survey123 mobile application. Below is our workflow:
- Open one of Esri's "For Export" basemaps in ArcGIS Online and select "Open in ArcGIS Pro."
- In ArcGIS Pro, right-click on the basemap layer and select "Share as Layer Package." Save the basemap to a local location.
- Add this basemap to a blank ArcGIS Pro project and remove the other basemaps, leaving only the basemap for export.
- In the "Map" section of the ribbon, select "Download Map," then download an area.
- Select "Include Basemap & Tile Layers."
Note: This process may take a while; the larger the area and the smaller the scale, the longer the export will take.
- Remove the previous "For Export" basemap file after obtaining the new basemap file with a local filepath.
- Open the polygon layers that have display issues in the Survey123 mobile app and access the attribute table of the polygon layer. Check either the layer itself or a copy for any fields with data types that could conflict with the ArcGIS Online Runtime version.
From here, remove the original basemap and open the "Create Mobile Map Package" tool. Create a mobile map package (MMPK) as a file.
From this point, the workflow for adding a custom basemap for offline data collection in the Survey123 mobile application remains the same: create a local file MMPK, upload the MMPK to ArcGIS Online, add the online MMPK to the linked content of Survey123, and add the locally stored MMPK file to the media folder of Survey123.
