Hi,
Sounds like a lovely setup, and honestly a very common one 🙂
All the Instagram accounts and the Facebook Page can sit in one Inbox. On Growth and Pro you can also choose which properties each person sees (Team › Agents).
When someone picks up a chat, they press Assign to me and their name shows on it, so the others know it's taken. And if someone else tries to reply there anyway, MirageCHAT asks them first: "This chat is Ana's, send anyway?". That's usualy what saves the double replies 😅
For the end of a shift: leave a private note in the chat (only your team sees it, never the guest), like "waiting for this guest to confirm arrival time", then tap your name on the chat and choose who takes over. They get notified straight away, on the phone app too.
Best regards,
Alice
