On the mobile site, I often tap on a thread but the one that opens is 2-3 lines higher.

Does that make sense? So there will be a list of Active threads:

AIBU to think pigs can fly?

Help with Potty training

Oh no, I'm covered in bees!

I'll click on "Bees" and it will take me to "pigs". I don't always notice straight away either. It's really annoying! The page isn't even jumping unless it happens in the split second that I click every time.

I am using android 5.1.1, standard Samsung browser.

Still happening for me. Anyone else?

I've just close safari and reopened it and it's stopped happening

Happens to me on Android.

Happening here too! Chrome on Android (Nexus 6P). It is so annoying.

Me too. Thought it was my phone. I'm on the mobile site on an android

Happening on desktop too - Windows/Chrome.

Seems to have started around the time the silly floating side bar came about.
Was fixed for a while, then came back with the font change.
When "Active" is loading, the page jumps 3 rows down when the Social Media stuff loads.
Same happens when you eventually get to click on the tread you wanted. As the thread loads, it's fine until the twitter and FB stuff loads.....
Can't say anything about ads cos I've got add blocker on so don't see them.
