The anecdote in the article is at odds with the title.
* In the anecdote, the problem is that the web version works better and the app is missing functionality.
* The title pays reference to an annoying observation about many products where the web version lacks functionality the app has.
Both are frustrating. If a company is going to bother to have both an app and a website, users deserve an experience where both are fully featured. It should be an professional embarrassment for a company to have to route users from the app to the site or vice versa because one is half-baked.
Have some God-damned professional pride and do it right.
The post is pointing out the irony. Corpos will tell you that "it works better in the app", and that is dubious at best.
