My folio has 23 articles. Sometimes when I update the larger articles, I receive a Network Failure that the article failed to upload. I click try again and all is well. This time, The upload has been in progress for over 20 minutes with no movement on the slider bar. I stopped the upload and open the folio on my iPad in Content Viewer. I was prompted to update the folio and the updates appeared in the article that produced the failure to upload error. Should I be worried? Is there a way to fix this without rebuilding the folio?
