Was this created via AI? It looks kind of... off to me. I think it's a combination of multiple factors - the 'c' is a bit wonky looking and has this strange rim lighting around it that doesn't really make much sense. Also, the cast shadows are clashing with the color blocking going on in the bottom-rightish third (?) of the connect icon, making things look really busy. Now that I'm really looking at it, it also seems like none of the shadows are consistent in their shading either, creating these extra visual lines that detract from the overall readability of the design.
Not trying to be overly critical or anything - I love the app and really appreciate all the work done here, and the icon does little to impact my experience with such a fantastic product. I just wanted to throw in my two cents on the matter.
