Hi there, this is my first app, so please be gentle. I submitted it on 6/16 (3 days ago) and I saw somewhere that it took 24-48 hours to be reviewed, and I believe that's when the people I invited to test it would start getting their email invitations. It's still at "Waiting for Review" on the Test Flight tab. Is this the same as THE "app review"? Or is it some "mini-review" for Test Flight? Either way, when should I start following up?
