Henry Neves-Charge as of yet no, I'm going to try and butter up an engineer on my team to see if they can help. ☺️ However looking at the documentation it appears project_id is an filter parameter you can send so if it's returning all the notes then there's probably either; a syntax error (but I'd assume you'd get an error instead of all notes), or a bug. I'll try on my side and report back.
