Patients have provided us screenshot proof that they have responded with simple responses like "C" and "Yes" for the automated system to ignore their confirmation. We also see proof of this on our end because we have a custom message that gets sent for those who are not confirmed. We have seen "C" get ignored for "Yes" to work later and the opposite ("yes" to get ignored, and "C" to work later). Inconsistency in an automated system means the system cannot be relied upon... upset patients = unhappy practice = bad weave client experience.
