We are using Assembly Esri.ArcGISRuntime, Version=220.127.116.11 and when in airplane mode mapview crashes when execute this line "async MapView.SetViewpointCenterAsync(gpsPosition, ApplicationConfig.MapMaxScale);"
Could you share some more information about the crash? (error message, stack trace etc).
Also is gspPosition a valid location?
Does this crash also occur with v100.5?
