[IMA SDK iOS] Can not receive ALL_ADS_COMPLETED event in background by Flutter

[Takeshi Kinami]

We are developing a radio app with Flutter framework. Since we introduced an audio ads feature in our latest release, there have been one problem regarding the event detection. Problem: The app fails to receive any events except LOADED and STARTED when it is playing in the background. As the result of it, it won't detect the ad completion. Once making the app running in the foreground, it will receive all the events at a time. (When the app is playing in the foreground, everything works fine. It can successfully receive all the events.) Enviroment: - Episodes can be played with Flutter's just_audio package. - Audio ads can be played with IMA SDK on native iOS AVPlayer. Expected Result: - App can detect all the events when playing both in the foreground and background. Actual Result: - App can detect all the events when playing in the foreground. However, App can not detect any events except LOADED and STARTED when playing in the background. We have been looking for the way to solve this problem for the last three weeks, so it would be greatly appreciated if you could provide us with any relating information.
