Why Letgo is not a user friendly application

Letgo is an app that lets users buy and sell things locally. This app is not user friendly and makes you want to delete it not long after downloading it. It sends you tons of notifications, has many unnecessary features and buttons, and usually doesnt aid in selling items whatsoever. This app has tons of terrible reviews online from very unhappy users and if you were to download it and attempt at using it you would understand why.
