I have a document (long one) with predefined styles. I want the users to use only these styles and at the same time I don´t want them to be able to change the given styles (alignment, indentation, spacing, colour, etc.). But when I restrict formatting and then I need to insert section breaks–next page (because I need to change page orientation) it´s not possible. After using formatting restrictions the „Breaks“ tab in Page layout is greyed out.
