Hello, have you enabled the automatic backup feature? Please check the MarginNote folder in the “Files” app on your iPad to see if there are any previous automatic backup files. If you find the backup files, we recommend downloading and installing the latest version of iTunes. Then, connect your iPad to your computer and export the MarginNote backup files. After exporting, please use a zip compression tool to compress the backup file and send it to us. We will help you with the data recovery.

Yeah, but i want to be able to use The app.
