Please make the latest version of the app compatible with iOS 9.?.?. Just like my favorite EA Sports games (UFC, NFS, NBA) are still compatible with it. I think there are still 999, 999, 999 iPads on iOS 9 with chess.com app installed. In the Beatles' words: don't let us down. And: it's only chess and that is all. Why should we feel the way we do.
I use the old version of the app on iOS 9. I acquired by signing in on other's updated iPad and availed of it on the App Store. Signed out and then it appeared on my purchased list on iPad 2. FYI only.
