In App Notifications (IANs) are another way to reach out to your users. IANs are messages that are displayed to the user when he enters your app, IANs can be either a small banner - like a SnackBar displayed on top or bottom of the screen - or fullscreen popups.
Pulsate delivers one IAN per user session, during "startSession" the SDK will download from the server one IAN and display it to the user. If the users was sent multiple IANs he will need to start multiple sessions to get them all - enter and exit your app multiple times. If the user was sent an IAN while he was in your App he will not receive it, the IAN is delivered only on session start, so the user will get the IAN the next time he enters your app.
