I still have this problem with Okular 21.08.3 installed as Flatpak on Debian Buster from Flathub. My testing shows that annotations made in Okular always assume the page is in 'Portrait' format. So if I open a PDF document with 'Landscape' format (without doing any rotation in Okular) and add some annotations; then even if the annotations appear correctly in Okular they will be rotated after saving and opening the PDF-file in another pdf viewer (such as the pdf.online web-app powered by PDFTRON or in Acrobat reader). This affects 'Typewriter' and 'Inline notes' because they show visible text on top of the PDF-pages.
