Which is why there was a firmware 4.3.11 released which did most likely also solve this issues.
It is known and we are planning improvements for the next beta.

Well, itās clear that it wasnāt resolved and with 4.4.4 itās still happening. Do you have this in mind or should I report it somewhere else?

If you put your phone into flight mode, turn on BLE and open the Nuki App. How long does it take until you get the status when you are in front of the door? Do you have Android or iOS?

Iām away from home these days, Iāll do it when I get back. In the meantime, letās see if any other colleague who suffers from these failures can try it.
Sorry but I canāt get anything, I donāt get any messages, maybe the test should be different.
I think I have managed to narrow down the issue for the lock not reporting the correct status and a significant delay when sending open command to the lock - I had Optimize locking set to Significantly reduced locking distance as this works for my lock and has the benefit of reducing battery usage and speeding up locking/unlocking. I have set the option back to Normal (default) and now the lock reports the correct status at all times and the delay when choosing to open the door is a second - the app still shows connecting however the lock now reacts almost instantly.
@Juergen do you want me to test and report back Reduced locking distance option in Optomize locking settings?
Lets follow up in a private conversation. Itās most likely not a general problem but specific do your setup (lift up handle & adjusted lock distance).
Original post has been updated with release notes for the Smart Lock (4th generation) Beta 4.4.5
This Beta includes an important fix for the physical button, ensuring that any manual input is recognized and handled properly. Next to that the motor strength has been adjusted to ensure that the latch stays pulled during an unlatch operation. Lastly adaptions have been made to the LED handling as several users reported that the LED behaved strange in random cases.
Please report your findings within this channel.
Thank you for your provided feedback! 
Hi, before to update to 4.4.5 the battery level was 40% and now after update is 60%. Any reason? I have the setting in NUKI POWER PACK.
EDIT: after 5 minutes the battery shows critical
There are two different versions of the Nuki Power Pack. The Smart Lock needs to perform a lock action in order to properly differentiate which PowerPack is inserted and adjust the battery percentage calculation accordingly. Therefore the battery % might not be accurate until a lock action has been executed after a reboot.

Hello,
Since the last official version I have a bug with my smart-lock 4 pro.
I decided to upgrade to the beta version (4.4.5) hoping that the problem is fixed because I have a lot of problems with my HOME ASSISTANT automations.
Here is a description of the bug, visible from the NUKI IOS application, or from mqtt, thread or matter.
When I unlock the lock, the state is unlocked for 2 seconds then the state goes directly back to locked while the lock is still unlocked.
Just checked and had lost Matter Connection on iPhone and checked on IPad it is available. Rebooted the iPhone still same issue even After update to 4.4.5.
Connection via Matter to HomeKit and MQTT to Home
Not sure what you mean by this. If your Smart Lock is not reachable in Apple Home on the iPhone, but reachable on the iPad, this is not something that Nuki has under control. Itās an Apple thing.
You are right just checked again and somehow itās okay now on all devices.
4.4.5 has fixed my issue with the front button intermittently not responding.
Hi
I received a notification about new beta 4.4.6. what are the improvments ?
I just installed 4.4.6 and I still have a problem. I canāt adjust the closing limit, whatever setting I put, the lock always goes all the way (the opening adjustment works).
If you have an idea Iām interested because in the old official version it worked
