This is happening fairly often. When I click on a post title to open a post, it takes me to a different post. Seems to always be sports scores. I'm not sure if it's always the same post it takes me to. I'll have to try to remember to actually note where it's taking me.

If I go back, it takes me back to where I was, and the post title indicates it has been opened, but if I tap it again, it takes me to the correct post.

It's not quite predictable, and it isn't repeatable.
