### 1/5 — 기기등록 안됨

*2026-06-06*

노트북 QR 인식도 안돼.
기기등록 안돼. 
뭐 어쩌라는건지……

### 1/5 — 기기등록이 안돼요

*2026-05-06*

기기등록이 안돼서 사용 자체가 안되는데 개선 좀 해주시죠

### 1/5 — 인증이 아예 안돼요

*2026-04-07*

정말 최악의 앱 ^^*

### 1/5 — IOS 기기변경 후 푸시 알람 수신 불가 문제

*2023-02-25*

최초 기기등록 후 다른 IOS 기기로 변경하여 사용을 시도하면, 기기가 다름에도 불구하고 이미 등록된 기기라고 나옵니다. 이 때문에 푸시 알람이 이전의 기기로 전송되는 문제가 있으니, 수동으로 기기등록을 해제할 수 있게끔 하거나, 기기 인식에 관한 로직을 개선해주시기 바랍니다.
