This is not normal,

Are you seeing this with test ad unit ids and the HelloWorld sample app?

Any update on this issue?

I was able to reproduce this behavior. In my case I notice this behavior only when the user clicks on the app icon to go back to the app. In case of foregrounding from swipe up or using the App Overview button in a 3 button navigation setup, I see the ad continues to play from where we left off. We will investigate this behavior further and get back to you. Thanks for the detailed report.

I was able to solve this by making a change to the AndroidManifest.xml file generated as part of the Unity Project. Once the Android Project is exported, navigate to the project and find the manifest under unityLibrary/manifests/AndroidManifest.xml. Then find the launchmode attribute(android:launchMode). Unity sets it to singleTask but the default Android launch mode should be standard. Change the value to standard and run the app. The video should now continue from where you left off when you click on the app icon to foreground.

Are you going to create a post-processing script or something to solve this inside the Admob package? Because we are not exporting the Android Project and I don't want to edit the Android Manifest file every time after the build is finished.

Thanks for your reply. I'll try at my side. And I wonder if this change will affect other aspects of the app's behavior.

After changing the launchMode to standard, the ads now display as expected. However, after closing an interstitial ad, the game restarts, which seems unintended.

Any way to solve this problem?
