Not until some point next year.
If you search the Community you will see a number of threads about a new BT and Sky (NOW TV) deal to share access to channels that is due to start in time for the 2019/20 football season.
The BT Sport app will be available on NOW TV devices (seperate subscription required), likewise NOW TV will be available via BTs YouView box.
I like many are fed up of waiting for this BT sport app on now TV, they have 4 out of the 6 fa cup games this weekend, I would move back to bt but their extortionate prices per a month is a No go. So I am going to get a kodi stick and pay £50 for the whole year for all the sports channels from both parties. As this as been promised to now TV for ages and nothing as been forthcoming.
