Issue since the 11.1.1 update

Whenever I login through disqus to comment on an article in an e-Newsletter, I am directed to a comment section for an entirely different article from either the same source, or a completely different article from a previous e-Newsletter from an entirely different source. This became an issue only after the 11.1.1 update. This was not previously an issue. I have the iPhone 7+. Apple, please look into this issue. Suggestions anyone?
