Avast VPN still asking to pay even with Premium Subscription

Hi,

I purchased Avast Premium Subscription and is activated on 3 out of 10 of my devices.

The First day I was able to use the VPN fine without an issue. Now I am all of a sudden being asked to pay for VPN and Antitrack even though it should be part of Premium subscription.

Why is this happening and how do I resolve this?
