No problem! Thanks for your work. I also use OSMAnd and enjoy hiking and mapping. I'm not that experienced either but feel free to reach out if you have questions.
osm.org/help and
osm.wiki/Get_help have some links for starting out and where to find help also.

For this changeset, a good comment could have been something like "additions/updates near Lewis and Clark Interpretive Center" or similar. Just something so other mappers (and yourself later on) can tell from the changeset comment what you have done.

Hello and welcome!
Could you please use more meaningful changeset comments? See osm.wiki/Good_changeset_comments
Thank you!

Hello! Could you please use meaningful changeset comments? “aass” does not help other mappers understand what you are doing. Please read osm.wiki/Good_changeset_comments
Thanks!
