Old issue with an invisible button is still there?? You see only images of logs and not a small arrow on the right side?
Right, I've never seen it on either of my Android 6 devices, but I can tap it if I guess the location. (Low, really low priority.)
"Retracted" cache listings are unrelated to Archived ones. "Retracted" is rare, by reviewer action, and happens (I believe) only if a cache has never been found. It's equivalent to "doesn't exist, never existed". On the website, attempting to view a retracted cache gives an "unpublished" message, the same as you'd see with a random GC number that hasn't yet been assigned. Via the API, it's likely equivalent to the code for "this GC number doesn't exist".
Hope that clarifies.

PS, GC6YB6K mentioned above is strange. It's archived, not retracted. But there's no Archive log, something I've never seen before.
