Class 2 NIC - No update on their SA Online Account

Hi, I register my client's through the CWF1 or SA1 online forms when are registered as their agent. However, their online record never seems to update for Class 2 NIC purposes. After submitting their SA return, I receive an amended tax calculation (SA100) back from HMRC, which excludes the Class 2. Can anyone shed some light on the reason behind this? Or offer an alternative approach? Thanks

Hi
If you are submitting a CWF1 they should be registered.
They would not be if you do an SA1.
We have not been informed of any ongoing issue with registrations.
Thankyou.
