Sorry to hear of the issues that you've been having with red button on BT sport. Does this issue happen when using the red button features on other channels or is just for BT Sport? Also do you have a V6 box or Tivo?
Thank you for popping back I am sorry you haven't received a private message and that you are still having issues, can you please explain to us when this is happening, have you reset the box if so did this help?
I know you have explained previously but due to the time between the posts, we will need to do some checks.
