After you book, you can immediately contact the expert through the chat facility on the app and schedule a time that works for both of you. 

The expert may not respond immediately, as they might be in middle of other consultations or classes. However, they will definitely respond within a few hours. 

As a second option, you can email the expert.

We send you an email connecting you with the expert right after you book, just hit 'reply all' in that email and get in touch.
