AdEventType triggering issue on iOS in Release mode

**Description:**

Hi. We’re having an issue with ads in the video.
We followed the example from pub.dev and are using the latest SDK version.
Here’s the critical problem:
	•	In debug mode, everything works fine. I can see all AdsManagerDelegate events in the logs, and everything fires as expected.
	•	In release mode (regardless of the flavor), not all AdsManagerDelegate events not fired. Due of this, some crucial cases—like handling ad completion—don’t trigger.

Also, after closing the ad (either by skipping or when it ends), the ad manager isn’t fully destroyed. I can tell because the video player’s control buttons become unclickable—almost like there’s an invisible widget blocking interactions.

I tried different things—moving managers around, checking if they get destroyed too early—but that’s not the issue. Something inside the library is preventing certain events from coming through in release mode.

### Also I tried example code - same issue.

**Android** - all works and all events fired as expected (both modes Debug\Release)

Thanks!

Release mode:

```

On the second video from example code, it stops playing, and a Google ad (10-sec pre-roll) starts playing in the background again.
Also, during the second video, a Google ad (10-sec pre-roll) was playing in the background.
