Mike, you might need to do a
manual claim, since the Oak has the current firmware version (6), is connected to the internet/particle (particle : connected), but isn't showing on the
particle dashboard. Can you double check the /device-id page again, as it should also have indicated the claim status - if it was 0, then you definitely need to do the manual claim ("c":0), whereas you can see from the screenshot below from one of my Oaks that it is a 1 ("c":1), indicating a successful claim.
