評価とレビュー

いつの間にか、自動スキャンが無料版では不可になった。仕様変更は構わないが、変更したならキチッと通知（更新内容に記載など）すべき。再インストールなど無駄なことをした。 過去、レビューで「使っている機能については満足している」とし星5の評価をしたが、今回の件で星1つにする。スキャンされていると思っていたのに、知らないうちに出来ていなかったなど信頼を毀損するのに十分なこと。

初回コメントの件は、その後個別に連絡を取り問題解決しました。ありがとうございます。スマホがアプリ起動制限を掛けていたためでした。 ほぼ自動スキャンされるようになりましたが、時々自動スキャンエラーになり、シールド設定も数日で外れてしまい警告が出て再設定を繰り返しています。きっとまたスマホ本体側の問題なのかなとは思います。。。危険サイトアクセスは検知してくれるので、うっかりタップしてしまった時も安心です。 2022/2/19 試用サブスクしましたが、自動スキャンを有効にしても、その時間にスキャンしてる様子がありません。 ログにもスキャン記録がありません。 自動スキャンされないのでしたら解約したいと思います。

以前から利用させていただいています。今回機種変し、今回もダウンロードさせていただきましたが、自動スキャンが有料になっており、設定できませんでした。しかし、同時に機種変（同じ機種）、ダウンロードした妹のスマホは何故か自動スキャンは無料のままです。私や妹どちらも有料であれば納得はするのですが、妹の方だけ無料のまま自動スキャンが使えるのは何故なのでしょうか…。
