It changes day to day. I haven't logged in to Twitter in over a decade. I haven't been able to go to mobile.twitter.com and do anything in years, just gives me a sign up page. I can follow a link to a tweet and use the search from there. But in the last week or so if I tap a tweet or a search result I get sent to a sign up page. This behavior varies over time.

A while ago Twitter liked to give me some kind of "connection" error in 50-80% of linked tweets, which miraculously disappeared once I logged in.

They still do this to me. It's a widely reported issue, that's been going on for years. It has to be intentional, at this point.

Yeah, I just started seeing this recently too. I blocked all those sign-up elements with UBlock but I still can't scroll. Refreshing the page once or twice usually makes it start working though.

Glorious webtech future.

I do, but when I click it, it requires me to log in.
