App Open Ad error on iPad simulator with iOS 26

[Ruben]

App Open Ad not showing with error "App open ad failed to present with error: Ad too large for window". This happens only on iPad running iOS 26.

Tested with both test and real ads on Xcode iPad simulator running iOS 26 with official GitHub example (https://github.com/googleads/googleads-mobile-ios-examples).

Additionally, please share the below details with us via reply to author option:
