We’ve had many complaints for books purchased from Amazon that results in illegible pages. The following is the note we eventually received from Amazon.
"After checking with our technical team for the printing issue. The defects you notified us about are visible in the uploaded file.
This issue is occurring due to the use of the problematic or restricted font, “Alegreya-Italic,” in the uploaded interior file.

Has this problem been reported before? Is there a way to fix this? Would appreciate advice please.
