To be honest, and I am talking as a reader here, it depends what kind of "note" you put there.
Putting something like a footnote at the end of a chapter, where you have some fun with your characters, like breaking the fourth wall, or giving a little sneak peak to the upcoming chapter or just something that goes on in the world, I will say that is fun and a little bonus for the reader
But putting under every chapter something like "Please Subscribe" or "Please Share" and so on, I dont know I always feel like the author is just too desperate - I mean watch some YouTube videos where the creators always start with 2 Minutes asking for donations and follows, then again in the video and at the end - it just gets annoying at some point
Now as I said, I say this from the view of a reader - as a writer I can understand that you want to have readers - heck I will admit, it would be nice to have readers for my own story, but i only see this 0 there ) - and I also have it in my YouTube videos, but only on a card on the end (except two videos) because I just don´t want to give the viewer the feel of me just wanting to do these videos/writings/etc to become famous and not because I have fun doing them.
But I would always put something in the description of the chapter
