Question: The Economist app
This concerns The Economist app which is used to download issues from a paid subscription. Normally, each edition is downloaded and accessed by tapping on the cover. This opens to the table of contents and tapping on a section in the ToC opens it up to access individual articles. Ever since an iOS upgrade, tapping on an individual section in the contents has no effect; in other words, I cannot access individual articles.
I am using a iPad Mini running iOS 11.1.1 and The Economist app version 4.0.14.
