I have application running ArcGIS Runtime 100.15. My application has some feature service layers. I am trying to identify features on mouse click. Sometimes it works, sometimes is not. identifyLayers or identifyLayersWithMaxResults methods from MapView does not generate IdentifyLayersStatusChanged event. I have a timer in my app and after 1 minute application hides busy indicator.
It stops somewhere in the code of these methods. I have tried to use Fiddler to check how request are moving but without success. Code stops working after first feature service layer or before first layer. Layer is not the same each time. It could depend on map scale because I am work with visible layers only. There is more than one visible layer always.
Usually it does not work at all after first unsuccessful identify. But I have some success after I try to move or scale map.
These feature service layers are public.
