I believe that Amazon Prime Video are covering the Lille v Slavia Prague (Tuesday 20 August) and Galatasaray v Young Boys (Tuesday 27 August) UEFA Champions League games.
TNT Sports appear to be covering the remaining games on those dates.
Prime have some live games now due to the amount of games and BBC have a highlights package. This could be coincidence with Warner Bros/Discovery hemorrhaging cash again and reselling content rights or UEFA making more packs available.
Amazon Prime Video have first pick of a Tuesday game - the packages were determined in 2022
@NigelB72 the following article covers the price agreed to be paid by BT Sports
@zulu17 ahh so it's the latter and more packs available.
