If so this can take up to 10 days for it to reach your account.
FYI that I do not work for NOW, I am simply a NOW customer trying to help I am a Community Contributor This means that I know a lot about the service and like you I am still a customer. For any account issues you’ll need to contact staff via customer support.
I believe the fight was on the 25th of September 2021, so the 10 day window has surpassed.
If there is nothing showing on your online NOW account under Mobile Sports Membership and you have tried the five permitted Sky Sports channels identified on this link below with the NOW App on your smartphone.
Then get in touch with NOW live chat for further help (use the green chat online button from the same link that i posted in the reply below).
