Ok, pc is fine. There are ways to watch it on the tv as well but let's not get stuck on that just now.
They've only just announced the live streaming service yesterday here:
https://www.afcb.co.uk/news/club-news/full-streaming-details-confirmed-for-202021/
In there it says "The club will announce in due course when the afcbTV Live site is up and running." so it looks like we can't sign up just yet but it should be available over the next few days.
As soon as the link to the sign up page for the streams is live I will post it here for you. Then we can complete the process.
