Acrobat iOS can’t convert news article

When I try to convert an Apple News article to PDF, it converts only the headline. 

When I'm viewing a news article, I tap the Share icon and the tap "Convert to PDF in Acrobat." It tells me: "Creating PDF. We'll let you know when it's ready."

After a short time, it says: "text(6).pdf was created and saved in Adobe cloud storage", and it says Open. I tap Open, and it opens a document in Acrobat, but the document contains only the article's headline. Below a checkmark inside a circle, it has a blue Back to Top button. 

Text(6).pdf is the name it gives the file it creates. Each time I try to convert an article, the number in that file name increases by one. It creates a matching text file.
