How to enable stereo recording

The documentation for the Capturing Stereo Audio from Built-In Microphones sample app mentions:

"Starting in iOS 14 and iPadOS 14, you can now capture stereo audio using the built-in microphones on supported devices."

And I saw a specific list of devices that support stereo recording here.
According to the list, an iPhone11 pro is supported.

But when I run the sample app on an iPhone11 pro, an iPhone 12, or an iPhone12 mini, the supportedPolarPatterns property for the built-in mic data source does not include the .stereo option.

Is there a way to enable it? Or am I using the wrong devices?

This problem was solved!

The factor was device language settings.

After I changed language from Japanese to English, it worked well.

Hi, we investigated this and found that the problem was in the sample code project for stereo capture. The API itself is available for any language, but the sample code incorrectly assumed English. This will be fixed.

@Sendo  - As part of stereo recording using WebView, have you been able to cache microphone permissions for each user? We wrote a demo app to record audio and each time the user gets the microphone permissions prompt.
