Good evening, everyone!
I regularly use my iPhone or iPad to enter text on Apple TV.
Indeed since iOS 11, iOS devices display a notification when you are on a text box on Apple TV, making it easier to enter search fields, email addresses or passwords (can you see me coming?)
For entering a password, the line is proposed above the iOS keyboard, this has the effect of opening 1Password but the input field remains empty, impossible to fill it automatically.
I don't know if this is due to a limitation or a bug on the iOS side or if it can be fixed by the 1Password development team.
Have a good evening/day
