Hi @Lord Spanien
Which version of Edge do you use? I searched and found a similar thread: Password import edge not working. From the replies below, it seems that it's a known issue of Edge in the latest Stable channel. I think edge://flags#PasswordImport
disappearing is caused by Edge update. For now, I suggest that you can provide feedback about this issue to Edge team by pressing Alt+Shift+I in Edge. They will check the feedback and improve the product continuously.
As a workaround, you can first go to passwords.google.com in Chrome to import the csv file. Then choose import from Google Chrome in Edge to import the password from Chrome to Edge directly.
