I closed the app during the migration progress and now the migration has stopped

During the migration process, you can use GoodNotes 5 and edit fully migrated documents but the app will need to stay open in the foreground. If you closed the app before the process was completed, you can resume the migration from the GoodNotes 5 setting:

1. Tap the Gear icon in the top-right corner of the Library view > Settings.
2. Tap "Import Data from GoodNotes 4." The migration will resume automatically.

Note: GoodNotes 5 will continue to migrate the rest of the documents and won't start over. You don't have to worry about duplicated content when resuming the migration from the Settings.
