BT Sport app after TNT rebrand

[Barisax18]

I currently have a contract for the BT Sport app with the £5 Ultimate add-on which I watch on my Apple TV. I am confused as to what happens when the TNT rebrand takes place on 18 July.  Is the BT Sport app simply renamed or, as I have seen suggested, will its content transfer to the Discovery+ app?  The letter I received today from BT “explaining” the rebrand seems to concentrate on BT TV subscriptions rather than those of us watching via the app.

No letter here, must be sending out in batches. 

All I know is that the BT Sport app will be closing and the TNT Sport channels will move into Discovery+.

The exact mechanics of that I don't think have been released yet, but I think it is most likely that it will work in a similar way and you can have a direct subscription. Whether or not 4K is an add on or a higher tier subscription instead remains to be seen.
