IOS8 support is coming end of next week.
Your current MagicalPad version is not updated for IOS8. if you upgrade to ISO8 you might see blank pages. Your data is not lost, it is a rendering difference that we fixed for the next release to support IOS8. So don’t do anything, just stop using the app for now if it happens. Once we release the build next week – depending on how fast Apple can approve it, all your data will come back. it is a rendering issue with IOS8 that your current version doesn’t know how to handle.
