According to previous comments on the same question, it appears that this is not due to external suppliers, but rather that this program must be maintained by the broadcasters. The best thing to do is to contact all affected broadcasters and write to them asking them to please adjust their programming in advance. If you check the ARD homepage now, there is nothing about a special daily show - not even on the station. But at 8:15 p.m. “The Bolzano Crime Story” will be broadcast there.
Of course, Swisscom will hardly do this live, but will still have a certain delay simply due to the data flow - but the main source seems to be the broadcasters.
And still off-topic: your post sounds to me as if your pulse and blood pressure are skyrocketing due to an incorrect EPG. This is not good, especially in times of Corona, as high blood pressure is a risk factor - so my recommendation: take a deep breath and enjoy the fact that you know the TV program better than the channels themselves🙂.
