With regard to the specific applications about which the Deputy has enquired, the Passport Service has contacted the applicants' parent directly and advised that the documents have been received.
The Passport Service regrets that the Passport Tracker recently experienced technical issues which resulted in the tracker not correctly updating a small number of applications. The Passport Service became aware of the issue earlier this month and initiated an investigation at that point. This issue has been identified and is now fixed. While it has not been possible to immediately update all affected applications on the tracker, this will happen automatically when these applications reach the next stage of the process.
