Was this even tested before it was released to the public? By @Jerome DCProud Lewis   Adobe has pre-release testers for all the Creative Suite programs and Acrobat. Occassionally I see Adobe announce for people to join the testing program.   Many of us community experts here in the forums are testers for Adobe, and many of us have been doing this since the 1980s and 1990s.    I can't recall much positive feedback from the testers before the "modern" Acrobat was released to the public. I know my comments back to the engineers were fairly extensive. Some things were improved (darkening the icons from a light gray to a dark gray, for example). But for the most part, the comments have fallen on deaf ears.   Over the past 18 months, I personally have continued to use and test the newest beta releases, but I often have to abandon them and switch to another computer that runs the "classic" interface. I have only so much time to donate to Adobe to dignose problems (and provide detailed bug reports and comments to the engineers). I, like most folks here, have a job to do. Working for free for Adobe is not on my to-do list.   3 suggestions: Disable the new Acrobat and revert back to the "classic" interface. I believe that all of the old functionality is still active there. Join the Acrobat beta testing group. I don't know where to direct you to join, but try searching for a public page in the Acrobat section of Adobe's website. Consider another brand of PDF editing software. The PDF file format was placed into the public domain about 15 years ago and since then, other companies have developed competing programs. Wikipedia has a decent list of other brands. One of our favorites is ABBY Fine Reader/PDF.   But note that none of these competing programs have all the features of Acrobat, so if you're in certain industries, you're really stuck with Adobe Acrobat. These industry-specific features include: Accessible PDFs and documents PDF forms Printing, graphic arts, and preflighting for print Security Digital signatures Automated PDF documents (aka, stuff like bank statements created from a database a on grand scale)   So see if any other alternative brand gets the job done for you. Be careful of the company's country of origin: you might not be able to install software from certain countries, which is the case here in the US for government computers.  Example: FoxIt is a Chinese company and usually is not allowed on our government clients' computers.   As always, don't forget to voice your comments on UserVoice and click the button to VOTE. That is the only place where Adobe takes notice of customers.   Let Adobe know: You can voice your opinion about the new interface at UserVoice: https://acrobat.uservoice.com/forums/590923-acrobat-for-windows-and-mac/suggestions/47082691-ditch-t...    Be sure to leave a comment about your experience with the new interface. They need to hear from users. And don't forget to click the VOTE button.   FYI, UserVoice is Adobe's official website where it reads and takes into account suggestions and complaints from users of its various products.  On the other hand, this community forum is a user-to-user help forum.   ...

Use a character style to set the underline. The style will automatically artifact it in the PDF.   New Character Style Name it Underline or whatever you want Set the Underline Options: checkmark to turn it on, and then choose whatever you want for thickness, distance from the baseline, color, etc.   ...

@Steve Werner is correct: The PDF identifier is applied in Acrobat, not in InDesign or its export settings.   But understand a key factor: the identifier doesn't actually certify anything because the process of validating a PDF for accessibility compliance can't be done by software alone. A human being must also evaluate the file and determine if accessibility requirements have been met.   Examples: software checker can only determine whether a file is tagged or not. Yes or No.  But a human is still needed to determine whether they are the correct tags. We have sample of documents with the identifier but are all P tags (no headings, lists, etc.) and a couple that aren't even tagged at all -- but they have the compliance identifier!   So think of the PDF/UA identifier as being a self-certifying marker: YOU, after validating and examining the file, declare that is is compliant.   The bigger question: are you willing to state that in your opinion the file meets PDF/UA accessibility requirements? You willing to stand up in court about that? If so, then go ahead and put the identifier on the file. If you're not so sure, then I'd avoide putting it on the file.   Most likely, your client doesn't know much about accessibility if they're asking for the identifier, unless they too will review and validate the file.   Just IMHO.   --Bevi Chagnon US Delegate to the ISO committees for PDF and PDF/UA   ...
