The new race season has started, and so we've subscribed to Discovery+, watching on the FireTV stick but subscribed on the website as I'm not sure if you can watch on anything or if it's limited to your FireTV stick if you subscribe via Amazon. No difference in price, so just went direct.
Watching the Women's Tour Down Under on demand, there were no adverts on the first stage, whereas watching the Dakar prologue (which was also on Eurosport) there were advert breaks (which could be fast forwarded through, unlike say CH4 or ITV catchup), so I guess it could go either way as we get into the busier part of the season.
