This is an add one. I manually created a login using the Linux client (8.7.0~12.BETA-1), and username, password and website are all stored.
However, if I go into it on the Android app (Android 12, 1Password v7.9.2), I can only see the username and website fields. If I now create new items, these are all fine, and previously created logins I can also see the password field for. It just seems like some glitch with this one entry.
1Password Version: 7.9.2
Extension Version: Not Provided
OS Version: 12
