Fixed
Creating and editing contacts works again. Since October 3, saving a new or changed contact only showed an error message and the change was not stored. This affected the contact form and the AI assistant. Saving works again. Contacts that were already saved were never affected; anything that could not be saved in the meantime needs to be entered once more.
Staff: “Request my own leave” only when it applies. Since October 3, the Staff page also showed the button to users who are not set up as staff members – the request then failed. It now appears again only when you have your own staff entry.
