While I think the improvement quoted above will help with the inconveniences alluded to in @ThreeStrikesTrigger’s post, their comment (quoted below) addresses one of my remaining questions/concerns with sharing vault items via send. After the send is completed and added to the recipient’s vault, I imagine the individual vault items will become stale / out of date once a password is reset or another attribute such as TOTP gets updated unless there is a sync mechanism with the shared vault item.
I’m still happy sharing a vault item is improving with the in-progress share vault item via send feature as it’ll add some convenience to sharing credentials (even though they may get stale).
