Insert and edit footers

The client requires a footer with page number centered and a confidentiality footer on the left of every page. Insert the footer across the document, unlink footers where a different appendix needs a separate note, set numbering to start at one on the first content page, and confirm the confidentiality line prints on exported PDF pages.

Before I circulate the report externally, make the footer clear for reviewers: put the page number centered, show the confidentiality notice on the left, ensure numbering starts at the executive summary, and flag any sections where footers are still linked so they don’t unintentionally omit the notice.

I reset page numbering to start at one on the executive summary, and suddenly the confidentiality footer disappeared from the appendix. I don’t know if it’s a linked footer, a different section, or an odd restart setting. What likely caused the footer to drop and how do I restore the confidentiality line across all content pages while keeping appendix footers separate where needed?

On multiple proposals I spend time reattaching the confidentiality footer and fixing broken page numbering after colleagues edit sections. I want one workflow so footers and numbering survive edits and handoffs. What consistent setup or pre‑send checklist will prevent lost footers and misnumbered pages when the document gets edited by others?
