Hi wwrr 👋
I'm sorry trying out 1Password hasn't been a smoother experience!
It sounds like you found the functionality to set the password parameters to align with the rules for each app/website, so I'm glad you were able to get that resolved!
As for the issue of the wrong password being saved, are you able to share screenshots of what's happening? Just be sure not to share any screenshots with sensitive information. You can also always email support@1password.com for help with anything that involves information you wouldn't want in a public forum.
I also agree with you on 1Password Community's registration form needing to offer some more guidance and we're working on improving that. Thanks for underscoring that this needs attention.
