I reached out to the aqara support as my U200 didn’t get the latest firmware update. This is there response. I guess from reading others topics here and in different threads, there has been quite a few issues with this version.

As I assumed and wrote in the neighboring topic, the firmware was most likely cancelled and a new one will be released.

My bad. I got an Server error while trying to create the post and it got duplicated.

The unlatch feature that came with V80 was a game changer to me.
I have home assistant unlock the U200 whenever someone is in the living/dining/kitchen area close to the door or getting close to the house and lock it again when leaving this area or the house using both presence and proximity.
Switched to v84 recently and noticed some slighly smoother operations.
