I would like to know this as well
I have just got the BT VIP tv package which includes all the sports and entertainment via Now TV to the STB which is great however the family really want Albi and I note it was offered by BT in the past so I am hoping the Now TV deal will get this channel soon as well ?
This is a great question and I have to agree with you.
After watching Harrow on Amazon prime I find it frustrating not having the channel available on NOW to watch the new season in April.
Have asked the very helpful staff at the NOW forum this question, hopefully get a positive reply!
