No notifications for shared account with door lock

Installed the door lock. I have all the functionality - lock and unlock, get notifications for door unlocked, locked, opened, closed. I shared the lock then with my wife. She can lock and unlock the door through her app but gets no notifications (she doesn’t even have the activity history when she’s in the lock section of the app). She has an iPhone 13.

I have verified that all the notifications in her app are toggled on. One thing I did notice is that under my list of devices the gateway shows as well as the lock. Under hers, only the lock shows. Is that the issue?
