have you gone to sport.optus.com.au and actually clicked sign up? If not, do that.
Pretty much what happens is you subscribe when you sign up (or later on if you're existing) and that enables you to activate the subsciption through the sport site.
If you've already done that, let me know what else you've done
Hey @Anne79 🙂
How did you go with your registration?
If you're still needing a hand with this you're most welcome to PM me & I'd be happy to help you out.
