Morning Joel,
The maps are created online in our ArcGIS Online account, they reference layers we have published to our ArcGIS server. The layers are added to the maps vis the Add->From Web option and point directly at the layer not the map service, i.e. http://gwonline.gov.gg/arcgis/rest/services/Water/gwWaterFittings/MapServer/0
The search still works on iPads which have not been upgraded.
Explorer for ArcGIS (10.2.8)
Explorer for ArcGIS (17.1.0)
We also have no information appearing when you have a map popup for the same layers.
