Click the date of the last post and it should take you there.
If you instead click the thread title it takes you to the first unread post. If you've read all posts in a thread that takes you to the first post instead of last for some reason, I think that can be modified somehow though.
only in case you marked all threads read at least once. if someone's logging in the first time, clicking the title will take him/her to the first post only, and the "go to first unread" button on the top right of the thread will redirect to a newer post. in my case, all threads showed some posts around 3rd-4th august as first unread posts, so that function is not working properly. anyway, after i marked all threads read, clicking the title took me to the new posts properly.

Cheers for the report.
That seems to be a bug in Tapatalk which we have no control over (looks like reddit embeds are not supported in Tapatalk), it works fine in desktop and mobile.
there's a fb video posted by badass and quoted by piotrr on the screenshot, too. it might not be displayed properly because it's in the moddle of a quote, though.
