### 5/5 — 기기인증할때 알림메세지

*2024-01-29*

가끔 필요할때마다 잘 쓰고 있었는데 
오랫만에 들어가니 기기인증을 하라는데 
알림메세지가 오질 않아요. 
설정에서 알림수신상태인데도 오질 않고
재전송을 눌러도 안옵니다.
혹시 문자로 오는건가요? 
그렇다면 번호가 차단되어 있을지 
모르니 번호를 알려주세요.

### 1/5 — 업뎃후 로딩무한반복이네요

*2014-07-14*

업뎃 전에는 정말 쏠쏠하게 잘 쓰고 있었는데 업뎃 후에 오히려 처음 화면에서 정보 수신중이라는 문구만 떠있고 무한 로딩하느라 어플을 이용할 수가 없네요. 어떻게 된 건가요?

### 5/5 — 좋네요 ^^

*2012-09-20*

좀더 사용해봐야 알겠지만 테스트 삼아 몇 번 시험해봤는데 유용한 앱 같아요..
