I use the app on android. I added a passport. But I can’t copy fields. There is no icon to copy. There is the copy button only for additional fields, but not for main.
I’m not able to make a screenshot coz the app prohibits to do it.
Sorry - I didn’t realize you were speaking about “Identity” entries. Somehow, I must have misinterpreted your first post.
Identity entries are not really designed for copying and pasting, as you would like to do. They are meant for auto-filling multiple-entry forms. You might try using a Secure Note entry instead - any text you enter here can easily be copied with a long press in the Android BW app.
