I need to change my confirmation text timing. I have the Android app and I do not have a feature that lets me change the confirmation text to an earlier time. As of right now, my client receive their confirmation for appointment only 1hr before appointment. I would like to change to 2 days before appointment. 

There is no notification feature in my app, but there is a notification feature in the Apple app. Is there a way to change this in the Android app? Or in the dashboard?
