Welcome to life after 40 - I’ve been an early adopter all my life, but my network hasn’t moved with me.
As a result joining Snapchat has no value for me.
So I tend to use apps that are friend-agnostic like this and TIkTok.
Side note: my fave messaging app is Confide, it only reveals redacted words as you run your finger over them, and then deletes. So it’s impossible to screenshot.
