In a situation like this, you need to check a few things:
- When your clients access your calendar, are they scheduling a date/time that falls within one of the blocks of time marked with "Available"? Remember that if a client tries to schedule an appointment that falls outside of the available block of time, they will not be able to do so.
- When your clients are scheduling/rescheduling, are they doing so more than 24 hours in advance? There is a "lockout" on your calendar and clients/prospects are not able to schedule any appointments (even when there is a block of time marked "available") if it is less than 24 hours in advance. This is to ensure that you don't have any surprises in your schedule and can maintain good time management.
If the above two conditions have been met, then please submit a support ticket in the Help Desk (from your coach dashboard > section "Support") where you provide examples of your clients (names) who are attempting to schedule unsuccessfully an appointment on your calendar and let us know the date and start/stop time they attempted to schedule their appointment for. We can then dig further to see what is causing this.
