Ask HN: Examples of websites that work well on mobile?

Hi, I'm curious of you have any examples of websites that are fairly complex and also work well on mobile. I feel like all social media websites are completely broken when using my phone. I see mostly these issues:

- broken navigation

- screen flickering

- scroll issues

- non-intuitive controls

- buggy input events that trigger unwanted actions

Do you know any websites that do it right?
