I've never had this issue before, but lately - within the last couple of months perhaps - I've been unable to email documents to my Kindle Paperwhite or Fire. I've checked over and over again to make sure my emails are verified; I've even changed the email to Kindle emails in case there was an issue. Nothing works. I've emailed dozens of documents to my Kindle over the years without any problem - what's changed?
They are word.doc and I've tried zipped and unzipped files.
