1. First, make sure you have set your work schedule.
Menu > Employees > Select employee > Workdays schedule
2. Menu > Settings > Appearance and language settings > Background intensity without schedule. Drag the slider all the way to the right.
3. Return to the menu where you create appointments. The time period without a schedule will appear shaded, dark gray.
The app allows you to create appointments outside of the schedule – in the shaded area – but you will be notified in this way.
