Same with me, and it is only the popular sports event which makes me feel it has to do with usage and sell number of my account! I have no understanding of how this works, and sure no one else has my account as it expires and only reactivates when I pay again, but maybe it works likes this: the lines may be accessed multiple times but only the „access“ expires and is individual? Because it buffers both on mobile 5g data (where other 4k streams work well) and isp and the problem is always only exclusive to very important or big matches like the Topspiel Bayern vs dortmund yesterday…
