I just double checked. My tracker updated on the 28th October to say background check was completed 25th October.Okay, thank you! I checked the background check says processing on the tracker. So hopefully it will update soon.
GCKey still shows as "Background check is processing" but I'm just waiting for eCOPR.
So, once you get to Final Decision the rest of the statuses don't matter. Now just to wait for portal emails.
