|Resolution||These objects are fully supported in the Salesforce1 mobile browser app, but they aren’t fully supported in any versions of the Salesforce1 downloadable apps for Android and iOS. Depending on the Salesforce1 for Android and Salesforce1 for iOS version, these objects may appear in the navigation menu but we don’t recommend using them.
