[Regression] Large / expanded ads are displayed instead of banners

[dase...@gmail.com]

For the last week or so, we have been receiving dozens of user complaints.

It seems that AdMob is showing large ads in our iOS app, whereas this is not a format we implemented. On this screen, we only use regular banners.

All the problematic ads are for the new iPhone and are from Apple, and served by Google Ads.

Are you aware of this issue?

@AdMob Can you please have your tech team look into this and advise ASAP?

This is extremely serious as it currently makes the game unplayable for thousands of users.

We use Google-Mobile-Ads-SDK (12.11.0)

Attached are some screenshots.

I cannot reproduce the bug on my devices, so I cannot share more technical information.
