Ultra Firmware 5.1.9 + iOS app Bugs

Firmware 5.1.9 broke the Lock’n’Go function on Smartlock Ultra. It does not work with Nuki Door Sensor after closing the door or after the time frame which is configured in the app (15 sec)

Firmware 5.1.9 broke Matter connection in iOS app after pressing the Button to activate Lock’n’Go

After pressing the button again, Smartlock opens the door and blocks the engine. Cannot drive the Smartlock or move the physical key.

iOS Nuki app shows no Matter connection. Device is offline

iOS Home app interaction with Smartlock works fine

Are there any other Nuki users who are experiencing these issues?
