They don’t ask you for biometric fee unless you have dependent in your application. And pcc police certificate is for those who have stayed outside their country for more that 6 months. I think you are good. You don’t need to worry just wait.
Some of them have received medical requests for the second time and after medical nothing yet. That’s why I was wondering if they require medical for the second time there might be delay and it will take a little bit longer.
