Yeah, seems to vary depending on kick off time and where they're sourcing the video from. I would suspect this game will be up on replay by late afternoon rather than 10pm or midnight, but you never really know in advance.
I've also tried the approach of avoiding the score before to watch back later (I might try it again tomorrow actually as don't think i'm going to catch it live...) but doesn't always work - you can bookmark the page - https://redtv.afc.co.uk/tv/lastmatch - which should take you directly to the replay of the last match - but usually when I then have to log in, having logged in it takes me back to the home page - cue thumbnail of player celebrating which suggests we've won, or thumbnail of player looking dejected which suggests we've lost. Also, sometimes it doesn't seem to play when I use the "last match" option. Can be quite frustrating when you've gone out of your way to avoid the score and then you basically find out just before you go to watch it.
