Sometimes rubber stamps aren't getting loaded on webviewer

Almost 9 out of 10 rubber stamp annotations are getting loaded. But sometimes it fails. I am using this to load stamps -

 this.viewerInstance.annotManager.importAnnotations(xfdf);

Is there a bug as we cannot identify the root cause of the following above issue.?

Hi,

Would you be able to share the XFDF and document with us of a time that it fails?

Also could you show us the code around your .importAnnotations(xfdf); call so that we can determine if its a timing issue.

Please make sure you’re calling importAnnotations(xfdf); in the documentLoaded event.

Thanks,
Logan
