I have a theory for that
Three likely scenarios. Since the files were transferred to Sydney after final decision was taken and just for triggering email
1. Since the files came in later they are towards the end of stack / queue whoever is supposed to work on them. And possibly they don’t see it that they just need “push of the button” and no real work without opening the files.
2. They do know the files just need PPR email but they have been procrastinating on them since they are not part of the stats anymore for them and they want to process newer files to get to 80% for later months
3. June candidates were picked to test their patience to the hilt. Somehow they have looked at number of pages here and they want to know what are the limits our patience can be tested.
