Hi @Dadot_71,
Thanks for reaching out. This behavior occurs because Apple Preview doesn't fully support interactive PDFs or embedded fonts from InDesign, which can cause fonts and layouts to display incorrectly. I'd suggest opening the exported interactive PDF in Adobe Acrobat, as it supports all interactive and font features properly.
Could you please confirm if the same issue appears on your end as well? If possible, please share an affected sample PDF file, so I can test it further.
Please give this a try and let me know how it goes.
