Buggy. Half the time, the app stuck at the start-up screen. Also, it is dumb to restrict the OTP to only one registered phone model and phone number. Isn't it enough that the user has to present the physical OTP card and has to enter the 4-digit code on the web site? These unnecessary restrictions make it really complicated to set up the OTP feature.

1번 인증에 1번 재부팅이 필요한 어플은 처음봤습니다. 별 1개도 아깝네요.
