All cards imported into bitwarden from lastpass didn’t get expiry filled, it went into the notes field and needed to manually move it to the right place
I also noticed LastPass’s export seems to be a bit off and imported funky. Not sure if this is something LastPass should be fixing or if Bitwarden should make theirs more adapting to. Probably both tbh…
It’s bitwarden’s import filters they need to update.
I opened ticket, they’ve put it in the bug tracker.
