I had a similar problem - app would start on my iPad and throw me out to the home screen (it was still active). I figured out that the app was trying to synchronize and was having issues. Here's what I did: 1. Turned on airplane mode. This allowed me to access the app. 2. Found the file that had not yet been synchronized, and copied the contents. (The file had a green arrow next to it) 3. Deleted the app. 4. Reinstalled from the App Store, signed on, and waited until my files had been synced. 5. Created a new file, and pasted the contents of my clipboard. Everything has worked fine since then.
