Migrate data from V3 to V4 on iOS 11 or higher

After updating to iOS 11, GoodNotes 3 will no longer open and the system will show a message that it is not compatible. Please invite the user to the TestFlight of both "GoodNotes - Notes & PDF" and "GoodNotes Free - Notes & PDF" to install a custom build that will help them migrate the data to V4.

After inviting them to TestFlight, please reply them with the snippet below

I've just sent you TestFlight invitations to install recovery versions that will replace GoodNotes 3 on your device. Please install the version (free or paid) that you were using. If you are not sure, just install both of them. Then please open the app and it will extract the data to iTunes File Sharing. Then please follow the on-screen instructions or this guide to migrate your data to GoodNotes 4. If you don't have GoodNotes 4, you can also send us your GoodNotes 3 data for recovery if they don't contain sensitive information.
