It's been a week since I received an approval email from Home Office (ceremony invitation).

But still cannot book a ceremony on Camden council website.
Data cannot be found.

Should I wait for some other email?
Called them today, they don't know much.

Does everyone have some delay usually? I thought everyone is able to book a ceremony relatively quickly.

When the council receives your certificate you will be able to book the ceremony - if they don't get it within a week or so you can try to contact UKVI about it. It has happened that the certificates have been delayed in the mail, or lost.

Have you tried popping over to their (physical) office and see if you can have a chat with somebody?
