### 1/5 — Could not register

*2020-06-26, version 1.0.0*

Using only English language, one can’t register on this app. Somehow Facebook, Line etc login don’t work. Google login worked, but I can’t register my name in English. How’s that for a multi lingual app?

### 3/5 — 登録画面

*2019-10-02, version 1.0.0*

登録画面にて"地域(非公開)"を入力して"はじめる"を押すと、再び初めの選択状態である北海道になり、数回押しても進めない。
