### 3/5 — App chưa hoàn thiện, UX chưa tốt

*2025-05-29*

App chưa hoàn thiện, UX chưa tốt. Có máy phải bật định vị thì mới kết nối được wifi trong khi ko có hướng dẫn kết nối trong các trường hợp. Nhạc nhiều nhưng kém chất gây confuse và khó dùng. Ko tạo dc playlist hoặc chọn favorites, trong khi nhiều bài midi gần như trùng tên gây khó khăn cho ng dùng. Ko thể xoá các bài kém nên khó quản lý bài. Khi nào chủ thớt fix xong thì đánh giá lại
