42s broke on my iPhone and I can't replace it because it's no longer in the App Store

[mick....@mac.com]

The 42s app suddenly doesn't work on my iPhone 6s and when I touch the icon all I get is a dialog box saying the app isn't available in the App Store anymore. I'm guessing it was rejected because it needs an update to bring it in line with the latest iOS version.

Please can this be fixed so that my favorite program is working again. Until then, life as I know it is over :-(.
