Question regarding the release form and DLC.

Getting near releasing a game on steam that is free but has a 2 euro DLC.

In the “Notification of UE4 Project Release Form” they ask “Will your product contain In-App Purchases?*”

Is steam DLC concidered an in-app purchase and if not do I have to make another release form for the cosmetic DLC?

Lastly does the 5% royalty fee apply if I get less than 3000 dollars quarterly? I’ve seen conflicting statements.

Thanks a lot for you answers beforehand.
