Calibration using app, both manual and automatic, can be done successfull, but sometimes unlocking fails afterward
The unlock movement will always start, but will halts on the way and sound like it skips a gear, while trying to resume motion
Anyone with some experience on this?
Attached videos of different behaviours
Note, the lock has been running fine for a few month and sometimes it will lock and unlock perfectly

I have similar issues with my U200 lock. I have been using it from about 8 month and everything was perfect but from approximately 3-4 weeks there are problems with proper locking/unlocking. Lock is trying to move the wheel but it can’t. When afterwards I am trying to open it manually it is extremely hard to turn the lock at first move. I had reset the lock, as well as other devices (M3 hub and button which is programmed for opening and closing the door lock) but situation has not been changed. What I can do with that? I am afraid it is because of firmware update (as I mentioned above, the lock had been working in the past perfectly).

Hi, thank you for reply and sorry for delay from my side. There is movie I made during calibration process. The lock sometimes could not even start the calibration. I have completely close the lock manually and then start the process but even then calibration is not always done properly. After many attempts finally I managed to finish the calibration. What could be important - sometimes, during calibration I see the i formation that Aqara is connected by Bluetooth.
There is also other thing, after calibration oppening or closing fail from time to time. Moreover, the sound when lock is working is strange. Movie attached.
Has your problem been solved?
My lock behaves similarly—it makes strange noises, the gears inside are noisy, and the lock won’t open or close.
I reported it to support, sent a video, proof of purchase, etc., but I haven’t heard back from support in several days.
The lock isn’t working and I don’t know what to do next.
The lock broke 13 months after purchase.
