I have a web map that, when opened in Explorer for iOS, initially loads the map with all of the layers turned ON. If I open the Map Layers menu item and toggle *any* layer, then the map refreshes itself into the proper state.
The Web Map uses a Dynamic Map Service (not a Feature Service) and does not override the Map Service's default visibility settings and the Map Service itself has appropriate defaultVisibility properties set on each layer, e.g.
"defaultVisibility": false, "subLayerIds": null, "minScale": 0, "maxScale": 0
The issue was originally observed on version 10.2.9 of the app. After upgrading to the most recent version (10.2.10), the problem remains.
Does anyone have a suggestion on how to work around this issue?
