I am scrolling All, I have scrolled a long way, and I tap on a post. 

Then I’m done, I tap < Back, and then accidentally tap < Communities. 

I end up on this screen: 

In Apollo, I used to be able to swipe the bottom of the screen to get right back where I am. 

In Voyager, I can only get back by tapping All in the list. 

I return to All, but I’m back at the top and lose my scrolling progress.
