Hello,

I tried to generally reproduce your issue and I was not able to. From looking at your import code though, you should not be importing the annotations at that point in time. The setDocumentXFDFRetriever API is meant to retrieve XFDF, not import it (only automatically after it returns). Once you have gotten the XFDF, you should just return it. Also, importAnnotations is async so it does return a promise and not an XFDF string.

It should just look something like this:

documentViewer.setDocumentXFDFRetriever(() => {
    return localStorage.getItem('annotations');
})

Perhaps give that a try and let me know how it goes!
