I've discovered my hosted feature layer views ("read-only views") are not visible in the ArcGIS Explorer mobile app (iOS). I made a test map containing only layer views and while I can open the map in Explorer, none of the layers are visible. I have another map with a mixture of regular feature layers and views. In Explorer, only the view layers for this map are not visible. For this latter example I can see all layers (including views) in the Collector App.
Anyone else experiencing this issue? Is this a known limitation for Explorer?
