Appointments are being filtered

By far the most common reason an appointment looks "gone" is a filter that is still on. Check these:
The status filter
The appointments overview lets you filter by status. Filtering on "Confirmed" hides cancelled and no-show appointments. Set the filter to All to see everything.
The date filter
Check the date range on the overview. You may be looking at a different period from the one you expect.
The search box
With a search term in the box, only matching appointments are shown. Clear the box to see them all.
The appointment was cancelled
Cancelled appointments are hidden from the schedule by default, but they are still in the appointments overview. Look for the ones with status Cancelled.
The appointment was never created
If a customer says they booked and there is nothing in the system, one of these happened:
- The payment failed and the appointment was never confirmed
- The customer did not finish the booking flow
- Something went technically wrong during booking
Ask the customer to check for a confirmation email. If they have one, the appointment exists. If they do not, the booking never completed.
Still cannot find it?
Get in touch through the feedback button, with the customer's email address and the date you expect the appointment to be on.
