Somewhat related: Does someone know what happened to the official AMA app for Android? It can't be found on the Play store anymore, but I still have it installed. I tried googling for info about it disappearing but came up empty. (It's a bit broken nowadays, questions and answers aren't loading. But I can still see the AMAs.)
