I have the Acrobat Reader DC App on my tab as well as Windows PC. Earlier I was able to highlight text and use other commenting tools on both devices. But now I can do that only on PC. When I try to do that in the Tab, the pop-up says the security features of the document don't allow changes. How can I resolve it?
Remove the protection from the document.
You can change the protection in Adobe Acrobat when you know the password.
Thank you Bernd. My protection doesn't allow changes. it's all written in grey.
Same here! On my mac I edited a form, saved it, next time I wanted to continue, it was impossible. Even if I am in the Fill&sign mode. I'd have to download it again and rewrite it all in one time. Can anyone help me out please?
