I bought a new iPhone, and installed Notion. It didn't download all my sounds right away. I was out of the house, and had some time, so decided to open Notion to work on a new piece. It started downloading my sound packs. Which pretty much ate what was left of my cell data limit for the month.

So, should be an option to only download over wifi, or at least have a warning come up. I did say restore purchases and do the downloads at home, but for some reason, it didn't complete there.
