Bad auto unlock on Nuki 4 pro

Hello,
I have had a Nuki 4 pro for a few days now. The auto unlock works very badly. I’m always standing in front of the door and have to wait. My wife and children have the same problem. We didn’t have this problem with my Nuki 2. It can’t be due to the app settings, as everyone has the same mobile phone and the same app as before. How can I speed this up?

Please contact our support via the Nuki App (Menu > Help > Contact Customer Support) as this is an individual problem and might require sharing logs and other sensitive data.

We have a similar issue with 4 Pro
Auto Unlock only unlocks the door but doesn’t unlatch the door.
We have to manually unlatch via app in 5 of 6 cases
Also new Beta Firmware has the same issue
Restarting and calibrating doesn’t help
