Cannot highlight using Acrobat Reader Pro DC version on iPad

[MoJo-Low]

Hello.  I have not been able to use highlight feature at all using the iPad Acrobat Reader at all for some time.  It's irritating me a lot. I pay for a DC subscription and you'd think the applications would work correctly.  I tap the pencil Botton, I tap comment, I tap highlighter, and it does nothing when I use my pencil or my finger except magnify the letter on the pdf.  What gives, experts of all things adobe?????????

It works fine on my iPad:

You only need to click the small pencil icon and ...

...you can mark-up what you want.

Yeah! That's what I did! I knowhow rouse it, but it doesn't work on certain pdfs! I've tried reformatting some and sometimes that works but it's absurd that it doesn't work for all!!

Thanks!

Is it possible to share one of those PDFs with us?
