A family of Microsoft word processing software products for creating web, email, and print documents.
The bot has given you a ton of stuff to try. The basic principle to creating different footers is that the footer must be unlinked from the footer in the previous section. Open the footer after the section break, then deselect Link to Previous.
If you are using Different first page and/or Different odd and even settings, you can have up to 3 different footers that must be unlinked from the previous section. Sometimes you must add temporary dummy pages to access every footer to unlink them.
Only use Section Breaks when they are absolutely necessary: to change page size, margins or orientation, to change headers and footers or to change the number of columns. To create a new page, just use a Page Break instead of a Section Break.
