It's not possible to rotate or flip a text zone or a text frame, as to fold it in 2 or 4 parts to make a booklet???
- please test a version that is currently maintained, preferably 24.2 - instead of rotating objects on the page, it might be better to use the options in the Print dialog to create your booklet, e.g. the number of pages per sheet, and the Brochure option: https://help.libreoffice.org/24.2/en-US/text/swriter/guide/print_brochure.html Please let us know if you think there actually is a bug once you test again, but if you have questions on how to print a brochure, please ask on https://ask.libreoffice.org/ Thank you!
