While we ask that developers pre-warm their apps to use App Check (i.e., generate the key and attestation object), we will still need to generate the assertion and execute a round trip with the backend to get the token sent with the sign in request. Testing on a real device shows that this averages somewhere within the range of approximate 0.6s to 1.0s.
