I thought we were supposed to drop the final p before nouns?
Yes. As the notes explain, this will be fixed in the future.
Sorry; I normally use the phone app, so I don't see the notes.
Yes, it is a bit of a nuisance that they are not available on the app. However, they do contain a lot of useful information, so it is worth using a web browser to read through them before starting on a new course unit.
