I just got my interview invitation last week.
Regarding application status, I've been talking on the phone with the admissions office and GAIC today. The information I got was that if any materials (GMAT, transcripts, or even application fees) that you have sent a while ago (weeks) did not reflect as received or paid on the status page, don't worry as this is normal since all the offices are pretty backlogged right now and it'll take weeks before they can confirm.
It will not affect your application since you have done your part. Hope this information helps if you're nervous or freaking out.
