Maybe old news but just noticed that all Autumn Internationals (except Ireland) including England to be shown exclusively via Amazon Prime Video.
Irelands games on Ch.4.

Anyone know if there's a way to watch the match, in full, after it's been streamed live by Amazon Prime?

From memory, it's just streamed live and there's no option to watch the whole thing later as live.

IIRC you can select the match from Prime after KO and watch live or from start. Can't remember about 'fast forward' through the preamble and not sure how long it is available for. That is on Prime, not sure about any other sources.

Ah OK, thanks.  Clearly I didn't look properly last year.

5) Which devices do you support & why can I no longer see live sports on my iOS or Android mobile device?

You can watch the matches on your TV, including Fire TV, BT TV and Talk Talk TV, on your mobile phone or tablet, or on your laptop. Live sport is supported on web browsers and on more than 650 connected devices via the Prime Video app, including compatible games consoles (PS3, PS4, Xbox One), set top boxes and media players (such as Google Chromecast, BT TV, Talk Talk TV, Virgin TV, Roku 3 and Apple TV), smart TVs, Blu-ray players (excluding Sony Bravia Blu-Ray Disc Player), tablets and mobile phones running iOS or Android. Amazon devices such as the Fire TV and Fire tablet also support live sport streaming.

I watch Amazon Prime via the Sky platform which they don't mention. BT TV, Apple, Fire, talktalk, Virgin, Roku all get a mentio but not Sky. I wonder why?

It's on the Prime Video help pages. Only Sky Q though.

Thanks. I couldn't see that. I have Sky Q so that's OK!

7) Can I record Rugby Autumn Nations Cup matches?

We do not currently provide the ability to record live streams. Match replays and highlights will be available within 2 hours after the match end. Full day highlights will be available within 2-3 hours after the last match of the day ends.

Hmmm, so if I miss Eng vs Aus live, I won't be able to watch it until about 9.30pm.  Hard to avoid the score for that long. 

(Thanks for the clarification though).
