Welcome to the 1Password Support Community. I appreciate you taking the time to try out 1Password and share your feedback here, and I'll be more than happy to pass it along to our development team for further consideration.
To clarify, the Send a copy feature makes a copy of the original item and sends it to another team member's Private vault. Any changes made to either item will not be reflected to the other, as you're aware. However, the ability to keep both the original and copy of an item up to date is something that has been requested before, so I'll be sure to pass this along as well for tracking purposes.
Send a copy
Thanks @ag_max for the reply and the clarification.
Apologies to you and the team for coming in a little hot with my comment. I was really surprised to find out that what seems like a simple sharing feature wasn't supported, but I probably should have been a bit more chill with my feedback.
Mostly I just want to give my customers a good experience, and I know after coming from Dashlane that they're going to say "Why can't I just share stuff with the people that need to see it?" If the tool's resistance to sharing things The Right Way is (comparatively) high, it's not hard to expect a return to password sharing via Slack being the result. Which admittedly is no worse than at least using the Send a copy feature, so hopefully I can at least get folks to use that if they're not willing to jump the "make a new Vault" hurdle.
No worries, and thanks again for providing your helpful feedback here. While the recommended approach of creating a new vault and inviting the individuals (or groups) who need access is tried and true, our development team is always looking to improve existing functionality or introduce additional secure sharing methods.
