Firebase Phone Auth > reCAPTCHA Enterprise won't disable after turning off in console (iOS, React Native)

Question

I'm using React Native (iOS) and Firebase Phone Authentication.

At one point, I enabled reCAPTCHA Enterprise from the Firebase Console via:

Authentication -> Phone -> App verification -> Enable reCAPTCHA Enterprise

After that, phone number auth started triggering reCAPTCHA verification. Later, I disabled reCAPTCHA Enterprise in the console, but Firebase still behaves as if it's enabled. Even though appVerificationDisabledForTesting = true is set in development, production builds continue showing this error:

'auth/unknown', '[auth/unknown] The reCAPTCHA SDK is not linked to your app. See https://cloud.google.com/recaptcha-enterprise/docs/instrument-ios-apps'

For a variety of reasons, the use of such generative AI tools is strictly disallowed on Stack Overflow. Please edit your post to remove and/or replace content that was generated using these tools. — esqew
