here in Italy there will be 7 additional channels dedicated to different disciplines (basketball, volleyball and beach, handball, football, racket sports & golf, combat sports, artistic sports -mainly gymnastics and diving) and 1 more channel in 4K (most likely a clone of Eurosport1)
they will start only on July, 26th, so we have to wait before we see if they're also on the D+ app (I think yes, because they're already announced on basically every Italian service, from our pay-tv Sky to the OTT like Tim Vision and DAZN)
4 years ago, we had those channels on Discovery+, but not on Eurosport Player
this time, since Eurosport Player is not active anymore, I think we are gonna watch those channels on the only platform still available (Discovery+, here we have to wait at least 2 more years to get the full Max app because of the existing deals betweek Sky Italia and HBO)
