Hi, we're experiencing an issue with the ReCaptcha SDK in our iOS app, which supports multiple regions. The issue arises when a user switches regions within the same session.

Steps to reproduce:
- User logs in to Region A (e.g., Italy) using the associated Site Key.
- User logs out and switches to Region B (e.g., France) with a different Site Key.
- The SDK throws an error: RecaptchaErrorInvalidSiteKey = 2.

We understand from the documentation that the SDK supports only one site key per session, but our Android app does not exhibit this issue. It seamlessly switches regions and Site Keys without errors. Also, if the iOS app is completely restarted, the new Site Key works fine.

However, switching regions within the same session consistently fails. Could you please assist us in resolving this issue? Are there any recommendations or workarounds for multi-region apps like ours?

Regards
