How can I add a service to an existing appointment?

Select the appointment you want to modify. Click on the “✎” icon in the bottom right corner. Then click on “Details“. In the Services section, click on the “✎“ icon. Choose the service or services. Save.

Then decide if you want to modify the duration of the appointment:

a. Modify: You will change the appointment time to a longer or shorter duration.

b. Keep: You will maintain the already set appointment time.
