Currently (unless it’s been changed since this) the only clear text instruction guiding new mobile users making their first observation explicitly says that it’s not necessary to add an identification. See the Android screenshots in this post: https://forum.inaturalist.org/t/guiding-new-users-without-scaring-them-off/2242/5
Changing the wording of that message, and adding a couple similar messages for those other key concepts would help a lot.
