No backwards compatibility

Suddenly the remote service only works with the latest version of the app, which requires iOS 9. This renders all of the older devices weve got around the house useless for browsing listings or controlling the cable box; it just shows "Unsupported Version of TV Remote" as the title for every show. The new version also displays a much smaller section of the grid, only half hour blocks on 5" devices.
