I am currently working with Presentations 2021 on a presentation.
- I started with a standard template
- Selected the page layout "Title and content"
- Typed some paragraphs of text into the text box
- Selected the entire textbox, opened the Format > Paragraph dialog and set Hyphenation to "always"
- Afterwards a couple of hyphens were added
- I saved the presentation, closed it and then re-opened it to find that all hyphens were gone.
Please find a test case attached: Thanks
