I am using Adobe reader android app version 11.7.1. I am able to highlight and underline texts but I don't know how to save my file because i can't see any button to save it. If i close my file all of my work gets disappeared please help me as soon as possible. Thank you
Adobe Acrobat automatically saves the file that you have closed. Could you please update to the latest version (16.0) and check if you are still observing the issue? It would be great if you could share the file with us.
