Hey All,
there are two parts to this. First problems with the latest My Fader 3. We have not seen this here. So if you are seeing cropped screen or strange issues or any other bugs with either of the latest versions of Master Fader 3 or My Fader 3, please post them or better yet, email them to DL1608.Feedback@mackie.com.
Now, My Fader 2 and Master Fader Classic are no longer the current version of the app. They are left on the store for compatibility with older older iPads and to allow users to upgrade to the latest at their convenience. We are not actively developing it, adding features or fixing bugs. We simply can't support older software forever. Here is the text from the My Fader 2.1 page in the app store.
>>> My Fader 2.1 is for use with iOS 6, 7 and 8. It is no longer supported or tested and is not designed for iOS 9 and is provided for compatibility with older installs only. For compatibility with the latest iOS software and hardware, search for and download the new Mackie My Fader 3.0. <<<
