Unfortunately a large number of customers have experienced an issue with the booking calendar: they may have reported being unable to get past the cookie consent form / page not loading, etc. The bottom line is that they have been unable to book. I’m very sorry about this.
We recently rolled out an update to Smoothbook: the issue is that an older version of the system is being erroneously retained (cached) in people’s browsers. Smoothbook is tested extensively before it’s updated and there is more than one mechanism in place to prevent exactly this issue taking place. This is very frustrating for me!
The solution for you and your users is to do a ‘hard reload’ on the page. On desktop this is ctrl / ⌘ + f5; on mobile there is usually a reload button which is indicated by a circular arrow sign.
I’m very sorry for any inconvenience caused.
