Hi Anthony I’ve sent you a pm on this with a helpful contact at Nikon UK. Hope it helps
I was away and only learned about the recall last month when I was able to log in here.
The day before, I found my Z8 had separated from my 24-70 and was not easy to reattach. I blamed myself until I came here and discovered the recall.
It was easy to register for the recall, and I quickly received an acknowledgement from Nikon UK:
"your advisory request has been placed in a queue to ensure the remedial parts are available prior to the return of your product."
This was on 29 June.
Since then, nothing.
My initial respect for Nikon's response to the problem has turned into disappointment.
