We've updated the Users -> Growth dashboard in App Insights to include the Login Dialog and App Center conversions. You can improve your app's Login Dialog conversions by following our Login checklist with policy and best practice guidelines. App Center conversions can be optimized by following our App Center guidelines.
Note that currently we can only count iOS native login dialog impressions when your app also uses the Facebook iOS SDK.
Facebook is committed to games and making life easier for game developers. Our new SDK for Unity allows you to seamlessly integrate Facebook across iOS, Android and web Unity games, so you can focus on what you do best--making games. We announced the SDK in August at Unity's developer conference, Unite, in Vancouver, BC. Parse announced their Unity SDK at the conference as well.
