Hi,

When you try delete an annotation and it doesn’t actually delete, are you still able to select the annotation on the document by clicking on it?

The recommended way to import/export annotations is with the ‘[importAnnotations](https://pdfjs.express/api/CoreControls.AnnotationManager.html#importAnnotations__anchor)’ and ‘[exportAnnotations](https://pdfjs.express/api/CoreControls.AnnotationManager.html#exportAnnotations__anchor)’ APIs. It’s not recommended to use ‘importAnnotCommand’.
