Well...hopefully they'll fix it or someone can send you the apk for the older version....
For future reference or other users. I was talking about being able to backup an app before installing an update. I use the
ES File explorer (device does not have to be rooted) to do this. It only backsup app not app data. This YouTube video tells you about using ES File explorer, but it prepped to start where they talk about file management [7m1s]. Other File Managers can do this as well. Hope it helps someone, just in case.
