To block your availability in case of an all-day event on your calendar (e.g. Out of Office days):
Go to the settings of your Vyte page (My Vyte Page or appointment type)
Go to the "Availability" tab
Activate the feature "Block bookings on busy all day events"
Don't forget to save your changes π
Make sure that your events are actually marked as "Busy" (or equivalent) in your calendar. This is often not the case by default for all-day events.
Warning: if you are setting this for a *team* appointment type, make sure to also enable this setting for the default availabilities of your booking pages, as Vyte will take both into consideration
