**PDF.js Express Version**  
8.1.0

**Detailed description of issue**  
If I create multiple rectangle annotations over a single pdf then only the first annotation is getting communicated . This was working fine in the previous version(7.3) . Do you think this can be an xfdf issue on your end. Please let me know your feedback on it.

**Expected behaviour**  
If I select more than one table and send xfdf info to server , all selected xfdf should have tag to it having the rect info.

**Does your issue happen with every document, or just one?**  
All documents have this issue.

**Code snippet**  
annotManager.on(  
“annotationChanged”,  
(annotations, action, { imported }) =\> {  
if (imported) return;  
if (action === “add” || action === “modify”) {  
this.annotationProcessing = true;  
}  
annotManager.exportAnnotCommand().then((xfdfString) =\> {  
this.XFDFStr = xfdfString;  
this.xmlArr.push(xfdfString);  
this.newXfdf = this.xmlArr.join();  
// newXfdf is the object we are sending to the backend

```
      });
    }
  );
```

Hey there,

You are using `exportAnnotCommand` which only exports new/changed annotations. We no not recommend using this function to export annotations, instead try `exportAnnotations`. We have a guide on this [here](https://pdfjs.express/documentation/annotation/import-export)

Let me know if switching to exportAnnotations works

Thanks!  
Logan
