Click [View History] tab on a Flow board, you're taken to e.g. https://www.mediawiki.org/w/index.php?title=Talk:Sandbox&action=board-history which has no link to return to viewing the board. This is part of https://mingle.corp.wikimedia.org/projects/flow/cards/420 "improve page navigation"
The WMF core features team tracks this bug on Mingle card https://mingle.corp.wikimedia.org/projects/flow/cards/659, but people from the community are welcome to contribute here and in Gerrit.
I talked to Brandon & May about this last week. This is actually exactly the same as current talk page behavior, e.g. https://en.wikipedia.org/w/index.php?title=Wikipedia_talk:Flow&action=history We could stick a link at the top, I guess, but they didn't seem convinced that it's a necessary affordance, what with browser back (or 2-finger swipe on iOS) :)
