Update 03/22/2022: Honestly, it isn't the app--but the entire Vanguard website that the app leverages doesn't work. For example, a "Maximize your contributions" feature doesn't even LOAD when I try to use it. The navigation is confusing; the explanations about your estimates aren't helpful; and the entire support experience is a failure. Vanguard needs to hire UX and app developers that can give this the TLC it needs.
