I don’t get any notification with this app version and Nuki 4 Pro with beta 4.4.0.
The Nuki was first installed in July, worked well and I got any configured notification.
Since these app or the Firmware 4.3.10 I didn’t got any notification. I took out the battery of the lock, recharged it fully, disabled the current notification and enabled all possible notifications.
The lock has a connection to the server and the auto unlock works. So this is not the problem.
