I downloaded the iOS 8 Gm, then clean restored in iTunes by selecting the IPSW. Before I did this I backed up to iCloud. Now I'm restoring from my iCloud backup and my document data is not appearing. This is particularly frustrating because I have invested hours upon hours in my notes. For the notes I'm using the app MindNode. What steps can I take toward getting my data back? The device in question is an iPad air and I was running the latest version of iOS 7.
