I’m experiencing a similar delay in updates.
Applied online from New Zealand to replace a lost passport, due to travel to UK on 31/08.
Application history
Identity details received 7:46am on 11 July 2022
Email sent to person confirming your identity 6:55am on 11 July 2022
Ask someone to confirm your identity 6:33am on 11 July 2022
Application submitted 6:33am on 11 July 2022
So it’s been over 3 weeks (which is nothing compared to what a lot of people have experienced, I’m sure!) so you’d hope that I’d at least get an update that the process has begun?
