 If you are already using in-app messages, then you will have to make the following changes to your code:
 
-1. `spawnInAppNotification` is no longer needed. In-app messages will be displayed automatically. Remove all `spawnInAppNotification` calls.
-2. Stop polling for in-app messages. The SDK will issue a callback using `config.inAppDelegate` [as explained above](#overriding-whether-to-show-or-skip-a-particular-in-app-message).
-3. Remove calls to 'IterableAPI.getInAppMessages()' and use `IterableAPI.inAppManager.getInAppMessages()` instead.
+1. `spawnInAppNotification` is no longer needed and will fail to compile. In-app messages are now displayed automatically.
+2. Stop polling for in-app messages using a timer, etc. The SDK will issue a callback using `config.inAppDelegate` [as explained above](#overriding-whether-to-show-or-skip-a-particular-in-app-message).
+3. If you want to handle all in-app messages manually, as before these changes, define an `inAppHandler` on `IterableConfig`. It should return `InAppShowResponse.skip` to prevent in-app messages from showing automatically. It can call `getInAppManager().getMessages()` to get the messages and `getInAppManager().showMessage(message)` to show a specific message.
