I can’t see a page or a button

“We could not find that page” or “Not found” means the link is out of date, the item was removed, or it belongs to a workspace you are not a member of.

“You do not have access” means your role doesn’t allow that action. Buttons you can’t use are hidden or disabled: see Roles and what they can do.

If something keeps failing, the error shows a “Reference”. Quote it when you contact support.
