Ugh. So many of our sentences are just bad. They were a part of a mass dump of data so many years ago, and never really screened apart from when they get reported, or rated on the website. We’ve been slowly building up our own corpus of sentences, but there is so much left to fix. Thanks for the report. We’ll replace it.
Btw, future update to the app will include a way to report these directly, which should help us find and fix the really egregious ones a lot quicker.
P.S. custom example sentence support, too! (Can’t wait for this feature!!!)
