I was wondering if there was any efforts to put the Imagery Hybrid basemap that is available on AGO and ArcGIS Pro into the Default Map Type options in Survey123.
The basemap that you are referring to is a vector basemap that can be enabled in the ArcGIS Online Organization Map Settings when logged in as an admin. Currently, Survey123 has not integrated vector basemaps into the options available when interacting with the Basemap Gallery within the Survey123 website options. You can refer to the help doc here for reference of apps that currently have support for vector basemaps from the Basemap Gallery...

Thanks for the info and documentation references. Are there any efforts to get the vector basemaps available?
