I did a survey123 and related feature report for Kootenay Boundary. Found a problem very strange.
While I set the geopoint to Kootenay Boundary, no matter manually click the map or preset by default value (as attachment), the feature report generation will be failed. But while I set the geopoint to Toronto, the feature report is working well. Out user in Kootenay Boundary tested it got the same result. Any clue? Thanks!
Fixed by changing base map on report template.
