I opened the post link in an incognito window and it looked fine. The main difference was a footer asking me to log in or sign up. Maybe all the stuff you remember was removed?
I have to be very careful how far I scroll down when reading threads. If I scroll a little beyond the last reply, I get a "See what's happening" full splash screen. Extremely frustrating when you have these X/? Posts and have no idea when the actual end is without checking for existence of the next.
Try scrolling down. Once you barely touch the bottom of the thread you’ll see an overlay that you can’t get rid of. Or at least I did.
Ah, thank you Xylakant and MSM. I don't see that, probably because of NextDNS (a cloud-based Pi-hole+).
You can get rid of the overlay by clicking "login" and then clicking "x" in the upper left corner rather than logging in.
