I can`t hightlight or underline pdf texts I have downloaded from Academic Journals on the Acrobat DC mobile. I select the highlight icon, I keep pressing my finger on the screen and nothing happens. Curiously enough, I can insert comments on the text (which makes me think that they are not encripted or protected). These are the only icons that are working ok:
a) Write comments - OK
b) Highlight - NO
c) Drawing - OK
d) Underline - NO
e)Crossing - NO
f) Add text - NO
g) Signature - NO
Could you help me with that?
BTW: it is possible to highlight the same text on my Desktop Acrobat DC

Which mobile app are you using? Acrobat Reader for Android, iOS or something else?
What is the version of the app?
What is the version of the operating system on your mobile device.
