[IMA-SDK iOS] Pre-roll Skipping Behavior Inquiry

[pineapplevine1]

Hi IMA Team,

I am currently testing ad playback using the IMA SDK on iOS. Below are the details of my test environment:
◆ Device  
- iPhone 16  
- iOS 26.01

◆ Sample App Used  
- https://github.com/googleads/googleads-ima-ios/tree/main/Swift/AdvancedExample

◆ Ad Tag Used  
- VMAP Pre-, Mid-, and Post-rolls, Single Ads  
- https://developers.google.com/interactive-media-ads/docs/sdks/android/client-side/tags#vmap-pre-,-mid-,-and-post-rolls,-single-ads

In this test, I replaced the sample app’s custom content with live content.
Then, I made an ad request after the mid-roll position had already been passed.
At that point, although the VMAP response included a pre-roll ad, it was skipped.

Is this kind of pre-roll skipping expected across all content types, including VOD?
Also, is this behavior consistent across other platforms such as Android and Web?

Thank you for your support.

Best regards,
