"There was an unsupported response from server."
Update as of October 4, 2024:
Apple has released a fix to this issue on iOS 18.0.1 which Okta has verified successfully. If an end user sees the above error, it is suggested that they upgrade to iOS 18.0.1 to resolve. Users and Administrators should not see any change in behavior between Okta Verify versions and iOS versions.
