Many updates later, still a poor app experience. Been a seller for four years now, nothing has changed except the fees and shipping costs have gone up. App continues to disobey DnD settings, so my phone lights up the room every night if I make a sale or get a message. App is still frustratingly sluggish and lack of dark mode shows they aren't listening to feedback. For how much money Mercari is milking from sellers, they should be able to develop a better performing app.
