My guess would be the way to trigger a call `runApp()` isn’t compatible with the App directory approach?  
The example has the two file method described [here](https://shiny.rstudio.com/articles/two-file.html) and [here](https://shiny.rstudio.com/articles/app-formats.html). Maybe someone else can comment if it only works with the Two-file method?
