The refresh of the book, ie the transfer of the booked settings in the live operation, is every 30 minutes each at 00 and 30 instead of the hour.
Premature refresh can be done under:
Settings -> Start Booking -> Start Booking -> Initiate Server push.
However, it is not advisable for performance reasons, because the delivery speed may be delayed due to the restructuring of the database at this time.
