Hang tight. The document will be scanned next week and as soon as it is, anyone can approve it, I.e your upgrade can be processed. I’ve read on here that people have received their passports 48 hours before their flight. Child renewals are moving a lot faster than first passports. My older son got his renewal within 2 weeks. I’m confident you’ll get your passport. It is unbelievably stressful and quite frankly it’s ridiculous that so many people are being put through this.
