Hi there, I am suspecting if your usage is wrong or it is a native API issue as that is where the error is originating from: https://github.com/firebase/firebase-ios-sdk/blob/a2db3aef68d454c2107c31bd24f9795baed71c1e/FirebaseAuth/Sources/Swift/AuthProvider/PhoneAuthProvider.swift#L81, could you please provide me a small snippet showing me how you are using verifyPhoneNumber?
