I am trying to upload a new book to Blurb and have waited for 3 hours and the status bar has not moved an iota. This book is 73 pages, 207-all JPEG photos. I used all Ariel font because I had trouble with another font before. I am running LR 6.9 on 64 bit Windows 10 with 12GB memory. Internet speed is 65Mbps and has not timed out. All photos are stored on an internal solid state hard drive. No error messages whatsoever. Ideas? Have there been issues reported with the new update? Please help, thanks.
Update - per the Blurb website trouble shooting, I tried converting the book to a PDF and that worked fine. Took just a few minutes of processing.
