Glad to have helped! I’ve been consistently amazed by this app, it’s really hard to catch it out. I tried really hard walking around an old stately home belonging to an Edwardian plant-hunter, tried it on all kinds of obscure plants and trees from Asia, the Americas and all over. I can’t remember it truly failing. I think it’s backed by a quite lively community of plant nerds - if something really is unusual, the community looks at the photos, and tries to solve it, and then that in turn teaches the app. It’s a great system.
