I am writing a document with several chapters. Each chapter title uses heading 1 and the chapters have the numbers 1 to 8.
All chapters are using header 1 so that I can build a table of contents.
At the end of the document, I have three appendix chapters. I want to use the numbering A, B, C for the appendix chapters.
To do so, I restart the numbering of the appendix section from 1 and, then, change its style to A, B, etc. However, all my headers become 1 and, even worse, the appendix section header numbering style is still 1, 2,...
