Just want to check back in on this as I think I might have caught the stream on a good day for the Fleetwood game. I've just decided to pay for the Swindon stream and am now encountering some of the issues mentioned by sinophile - juddery audio and picture and periodic buffering that is worse than the Fleetwood game for sure.

I noticed that the following message has appeared when you go to buy a streaming pass:
"Please be advised, however, that a connectivity issue - outside the club’s control - and which has been affecting ours and a small number of other clubs' commentary services recently, will not be resolved in time for today’s game. This means supporters will experience a reduction in sound quality on their commentary/live stream this afternoon. Please be assured that we share fans' frustrations and are in regular dialogue with the relevant parties to ensure this issue is corrected as soon as possible."

Sounds like there are indeed issues, so hopefully they are resolved!
