If your child is using an Android smartphone/tablet, a 4G LTE mobile phone, or a miraie f, you can individually unlock (allow the use of) the apps by accessing the "Administrator Page" [管理者ページ].
For details, please refer to the information below.
From the parent’s smartphone or computer, access the "Administrator Page" [管理者ページ] of "Anshin Filter for au" [あんしんフィルター for au]
"Enter the administrator ID (email address) " and "password", check the box "I am not a robot" [私はロボットではありません] then tap on "Login" [ログイン].
Tap on "App-specific settings" [アプリ別設定].
Tap on "Regulation" [規制] in the LINE column.
Tap on "Allow individually" [個別に許可].
Confirm that LINE is displayed as "Allowed" [許可] in the "Individually Set Apps" section, and tap on "Save Settings" [設定を保存する].
The above completes the setting for the LINE usage permission.
Although the steps were demonstrated on a smartphone screen, the same apply when using a PC.
