The F1 Qualifying repeat was scheduled on the TV Guide for 2.30pm, but it didn't start until around 2.45pm.
The live stream is currently playing for me through the NOW TV Guide live Sky Sports F1 channel on my Chromecast Google TV.
Are you seeing the live stream on your playback devices?
What playback devices have you tried and I am assuming you are not using a NOW Mobile Sports Membership which doesn't cover Sky Sports F1 channel.
If using a PC are you going through the NOW TV Guide to access the live Sky Sports F1 channel?
I can't check on a PC internet browser because I don't own a PC or Mac, but my Chromecast Google TV and Amazon Fire Stick is currently showing the F1 qualifying repeat on the Sky Sports F1 channel through the TV Guide on the NOW App.
