Quick questions,

No. A guest opens the private link with their own name on their phone and can read the invitation, pick a photo slot and leave a message straight away — even inside Zalo.

You add guest names in the studio and each person gets their own link. When they open it, the invitation greets them ("Dear Minh Anh,") and their RSVP is tied to them.

You see them in the "Not sure" group and can message them any time. The guest can reopen the same link to change their answer; no new link is needed.

The other person can open the invitation, but the RSVP still carries the original guest's name. You can change that guest's link in the studio if needed.

You set a start time, an end time and the length of each slot (15 minutes by default). One group of guests holds each slot, and a slot that is taken locks itself.

The guest taps "Change slot" on the invitation and picks a free one. The old slot opens up for others right away.
