ケース番号：60588522 の問い合わせにて
「おかえりなさい」のポップアップを管理コンソールより一括で無効にする機能は、現状実装がされておりませんでした。
との回答をいただきました。
以下の理由により、実装するように改善をお願いいたします。
・我々が知る範囲でも複数自治体で被害が出ている
・chromeの根本と言っても良い「拡張機能」がchromeOSの「おかえりなさい機能」で無効化されるのは不具合と認識している
以上、よろしくお願いいたします。
You might want to post this to the Feature Ideas section here. Doing so will allow it to be upvoted by others and possibly considered as a future feature enhancement.
If you do not already have access, you need to request it first. See https://www.googlecloudcommunity.com/gc/custom/page/page-id/Workspace-Feature-Ideas-FAQ for how to do that.
Once you have access, go to https://www.googlecloudcommunity.com/gc/Feature-Ideas/gh-p/workspace-ideas-group . There, you can upvote and comment on any similar idea, or post a new idea.
If you are submitting a feature idea, be sure to explain the problem that you’re trying to solve with the feature idea, not just the idea itself. For example, saying “when my users are trying to do ‘A’, they often get confused by the fact that the buttons to do ‘X’ and to do ‘Y’ look quite similar to each other, which leads to this unintended consequence” is far more likely to get fixed than a feature idea that just says “change the color of the button ‘Y’”.
Cheers,
