No more notification when my Schlage lock is unlocked

Works fine till recently.
The batteries are fine, I can see full event in the SmartThings API. (Who unlocked the lock)

Notifications are allowed on my IPhone, everything is up to date. Notifications for the lock is enabled in the SmartThings app.

I rebooted the hub, replaced the batteries, restarted the iPhone. Switched off the back on the notifications.
Nothing helped so far.

Any clues someone?

Your lock may have transitioned to an Edge driver and that might be related. On the device’s info panel, click on the 3 dot menu. If there is a Driver option, what driver is the lock using? Also, what model is your Schlage lock?

It’s a Schlage Connect Z-wave.
