There was a post made detailing whihc email address to reach out to if you purchased the first board, with the order number. I think from the order number they were determining exactly which parts were in need of replacement and sending those. (Some got sent with shorter retainer clip for the NVMe drive, it sounds like you've got one of the earlier ones that had the taller clip.)
I submitted my info that day but I haven't see/heard anything yet (I really just want the revised cable, the old one gets easily pinched and the drive disappears for me then.) From what i understand the new bard kit revision is now the one sent/received whenever you order one from the Pine store.
I was just thinking about this today, glad so see another post. I must have missed that email since I have a PBP from November and I have the original NVMe adapter but never received any additional parts.Thankfully I haven't been in a huge hurry to use an NVMe drive but it would be nice to be able to when needed. Is it just the general support email address?
