I have messaged the twitter help folk and had a response after trying many times without any luck to call them (still waiting on a call back).
They have said the passports are marked as received although still not showing as such on the tracker page.
Both applications sent within 20 minutes but two different offices to send the expired passports. Anyway, have to wait until next Wednesday to escalate as that’s when the two weeks from travel bit kicks in fingers firmly crossed! In my minds eye 5 weeks was tight but not stressful very last minute to book to go away this year for obvious reasons just hope we get this over the line or one almighty disappointed family and a very expensive mistake to leave it so late to renew two of the kids passports!
