This link is no longer valid

yes I have this problem too. 

​@bmoates Sorry for the trouble. Could you please contact our support and share your booking link, so we can check what’s wrong?

Yes, I experienced something similar earlier today. Newly created scheduler links were working at first, but later started showing an error page when accessed. It may be a temporary issue on Zoom's scheduling service rather than a problem with your individual schedules.

Have you tried opening the links in a different browser or an incognito window? If multiple links are affected, it seems more likely to be a platform-side issue. Hopefully Zoom resolves it soon.
