No Ebon Flintlock (SoT)

I started watching the April 16th Inside Xbox stream only two minutes after the stream started. I still haven't received the ebon flintlock in Sea of Thieves, I waited the full week to check, still isn't there. I understand many people are running into this
issue but it says I need to make a claim within two weeks, is this how I do that? My Xbox gamertag is . My Mixer account is definitely linked to my Microsoft Xbox account.

Thanks in advance.
