ダウンロードさえ出来れば入国できる?

米国でアプリを開くとNetwork Connection Errorがでる。調べると、日本のネットワークにつながればエラーがなくなるらしい? だったらなぜそう書かない? これでどんだけの人間が不便を被ると思ってる? ユーザー目線ゼロの役立たずのアプリ。

Network Connection Error

If you want to (or must) use the Exposure Notification system on iOS in Japan, you must use this app. If you attempt to register in the app before you arrive, you will get an unhelpful “Network Connection Error”.

The app will not let you proceed unless you are connected via a Japanese network. Note that international roaming on a foreign cellular network will not work. You must connect via a WiFi network in Japan or via a Japanese cellular network.

Network error outside Japan

The Japanese government is so incompetent with a lot of things but especially with anything IT. This app is one of those examples. This app's network error message needs to let people know that this happens when they try to use it outside Japan.

Just a annoyance

You are forced to download this app when you enter Japan and won’t do anything afterward.

When I try to register it says network error
