I am pretty sure that Apple News doesn’t understand the meaning of blocked.
I blocked a channel in Apple News, now as I understand the reason I blocked the channel was because I didn’t want to see articles from that channel in my news stream.
However despite blocking the channel, the stories still appear in the stream.
I can still see the headline, the only difference is that the story picture has been replaced with the words You blocked this channel. The story is still a live link, yes you get a warning, but I am not sure that this would count as blocking.
The way I would like it to work, is that when I block a channel I don’t ever see it again. There could be a list of blocked channels, in settings, but otherwise I wouldn’t want to see it.
If I hide photos in Photos then I don’t see the hidden photographs, but I can access them if I need to. I don’t believe I can hide channels in Apple News.
So, though I have blocked stuff, I still see it, what is that about.
