Just Called HM Passport Office. Apparently, there’s a backlog currently. When they send the text the passports are printed and ready to be sent out. BUT are waiting for TNT to pick up and deliver the passport. (This is where the backlog is)
The advisor said to wait until Monday (21st) to see if anything has changed i.e. text/email from TNT or the tracking works. – if nothing appears to give them a call and they’ll chase it up?
UPDATE: Still no passport/unable to track still
