Finally spoke to someone at Glasgow.
My sons application hasn’t progressed because I made the application and not his mother since we are not married.
Even though it is a renewal and they can see his birth cerficate from his application in 2015 they cannot accept this, so now I have to wait 3-5 working days for a letter to come to then send his full birth certificate back.
My son has my name, both mum and me have passports what a absolute f’ing joke!
