Just because it only happens on bt sport does not mean that the issue is bt, the fix will apparently come with a firmware update on the chromecast which suggests it is Google’s end, the problem we have is that if it’s just BT sport that is causing the issue then google are not going to be in any rush to push out the firmware update. I’m not sure what percentage of people with chromecast use bt sport probably a large percentage of the uk users but it’s probably a low percentage when you consider the worldwide users and the firmware update will be pushed out worldwide.
This is a BT sport app issue as this doesn’t happen on anything else I chromecast
How then do you explain that it doesn't happen with the first generation Chromecast (looks like a memory stick)?
That's certainly an interesting point pottyperson, but I'm afraid that I don't approve of rep begging.
The issue does exist and is specific to the BT sport app.
No, it's specific to the second gen Chromecast. Have a look at Messages 28, 36 & 45 above for enlightenment.
