Analysis is great! Save button not working – Free Chess App Review

I love the analysis feature on this app. I searched for a new analyzer because chess.com got rid of its free analyzer. This app has tons of great features, such as a best move indicator against the computer, or as its called in the game suggestions. The two things I dislike is that there is no way to offer a draw. The second is that the save button only sometimes works. Please fix!
