I'll go one further, "only notify me if someone actually sends text or a file" I don#t need numerous notifications about hearts or any other reactions, they don't give me any useful info beyond possibly thumbs up/down for agree/disagree, I might be old but I don't read emoji, to mer they are just a lot of visual noise, and sadly my ADD does not aprichiate that
