Thanks for using the forums to get this issue with your HUB 4 looked into, I am sorry its having some issues with the activation. I understand how frustrating this must be for you! We were having some issues with this a few days ago that affected a large amount of customers, this has since been resolved by our faults team though. Can I ask how things are on your side now please? If you still need help I will be happy to do so for you.
