Maneuver through community question

If I click on a post and want to go back, how do I do it? Seems like a silly question but the back button takes me out of community not to where I left off. There’s no breadcrumbs to click on.
What am I missing?
It’s probably super obvious…

I need a little more info to understand your question. Are you talking about clicking on a topic in a list. When I do this and then click the browser back button, it takes me back to the list. If you need to go back to the enclosing category, you can also click the category (eg Ask the Community") at the top of the topic.

Phone back button. Works the same as the arrow at the top left.
