Not true. I just added a random number of blocked sources and none of them were replaced. Currently blocking 5 or 6 different sites. Chrome version 65.0.3325.181.
Heh, I guess they prefer you. Just tested with chromium 65.0.3325.181 and the bug is there. Have you tried leaving and coming back to the preference page?
Yes, I have. Quit and restarted Chrome. There's no bug. I'm afraid there's no way to reproduce the behaviour you describe.
I have Fox News, Daily Mail, CNN, and a number of other sources blocked. No issues whatsoever.
Interesting. So it's only broken for a small subset of people, which explains why they never even bothered answering. I suppose it is tied to my account then, since various laptops and browsers gave me the same behavior.
Which isn't sufficient as their feed keeps showing material from Daily Mail and similar garbage. Skipping it manually isn't a problem, but it does take the space of meaningful news reports.
Users sent countless bug reports and started many threads on their forums since around June 2017, no reply. Nowadays I just aggregate aljazeera and reuters, way more efficient.
