Hello Everyone! Just received my new passport, I will post my timeline below as a reference.
My documents took about two full weeks to be logged as delivered, then another week and a half to get the photo rejected, so immediately updated with another, only to get approved the next day. The delivery details took another week to become available and the actual delivery was one day later than it said on the webste. Still waiting on the return of supporting documents. Recieved absolutely no messages or emails from TNT, just got documents in the mailbox.
Good Luck everybody!
