Deliver a gallery to your client
Open the gallery and use Share link, or go to Settings on the gallery to deliver it.
Delivering asks "Deliver this gallery?" first. If the client has no email on file it tells you "Nobody will be emailed", so you know to pass the link on yourself.
If you share a link too early the app stops the client seeing an unfinished gallery, and tells you why with "Gallery isn't live yet" and "No one can open this link yet". That is the guard working, not a bug.
