My mount had bricked after updating to firmware 1.4. I reached out to support and they gave me a different version of firmware. That fixed that issue!
Also, I noticed that Nikon lens would disconnect with the body sometimes, especially if I accidentally touch the "mounting lock" lever while using the camera.
I took the mount and noticed that the lever has a very weak contact with the very tiny circuit board right behind the lever.
You have to disassemble (would void warranty -- if there is one..) first in the nikon side, and little bit of unscrewing at the bottom mount side to fully expose the lever. I added a few layers of tapes to elevate the lever's height against the trigger. Now it works reliably!
