Here are the steps to remove an added storage connection in iAnnotate.
1. Navigate to the storage library
2. Tap the circle next to the storage location you want to remove so that a check appears in the circle.
3. Tap the trash icon at the bottom of the page and confirm delete.
All local files are not backed up and will be lost if you remove the local storage connection.
Cloud Connections will remove the connection from your device, but any documents will still be available in the cloud drive outside of iAnnotate. To permanently remove documents in a cloud drive the documents must be deleted or the cloud drive subscription canceled and archived.
