Unblock account email link -> error page url already used

When a user is blocked, they receive an email where they can click a link to unblock their account. When clicking the link (for the first time), they are taken to an error page “Authentication Error. This URL can be used only once”. Their account is however unblocked successfully.

Is this a bug on Auth0’s side? Or is there something we can do about it?

Url looks like: https://CUSTOM_DOMAIN/lo/unblock?ticket=TICKET_ID

The error page doesnt seem to have all the new experience styling either.
