In my experience it depends on how you open the tweet. When I click Twitter links online, scrolling works. The moment I switch tweet, scrolling becomes restricted again. Trying to scroll through someone’s profile is also very restricted, I can only scroll past maybe 3-5 tweets? I’ve now clarified in my OP that this happens in most cases, but not always. Yes, it’s PC in my case. On mobile it allows me to scroll through someone’s profile but scrolling through replies to a tweet seems to be limited (a huge “please sign in” overlay is displayed eventually which I cannot close).
