It's normal. It takes a while for all the systems to sync up. Sometimes you get DM emails while your GCKEY still says in process and sometimes it's the other way around. I had my interview scheduled before I got the DM, lol.My GCKey updated and said I was approved with the message "Your application was approved. Check your messages below for details.". However, there are no messages below. Any ideas?
Edit: I am the principal applicant
No need to worry, it can take a few days.
