Realised notifications have been implemented in the Android app, as I received one for an answer to my question. However, when I clicked on the notification (the app wasn't in the foreground), the app opened, but displayed the previous view I was on.
I had to open the menu, return to the feeds view, and search for the new activity. No in-app top-right notification was displayed either.
Would be less confusing and useful to have the answer loaded and perhaps scrolled-to-focus, when the Android notification is selected.
