			I should clarify - The jobs are all marking as "successfully sent" on Calibre's end. So, I guess they're being rejected by Amazon for some reason?  (Even though the e-mail is added as approved?)

			covers not showing up is simply amazon trying to dissuade you from side-loading, so you give them more money. Use a USB cable, you will have much better results.

			@d56alpine You can't send KFX files via e-mail     Just like you can't send AZW3. And the reason why Amazon sends those verify request e-mails is that you're probably using kindle email address that Amazon considers "unsafe" because it was derived directly from you Amazon account email address: like name_surname@whatever.com >>> name_surname@kindle.com Go to amazon.com/myk, login in asked to do that and under Devices edit the email address associated with that Kindle device you want to send books to and add something extra like: name_surname_mykindle1234@kindle.com Then in the future use that new Kindle email address (name_surname_mykindle1234@kindle.com) and you shouldn't need to verify. |

			I just got warned about this and I suppose if Amazon doesn't want to display covers, that's fine with me--I only wish they would have an option to stop displaying thumbnails at all, because it only looks like crap because they insist on displaying them. I want the old list view back with just text but I know it won't happen.

			Noticed that the /amazon-cover-bug and /system/thumbnail folders were forever growing (for me, around 3000 entries with only 100-some books currently on the reader) so I submitted an enhancement request to clean them up. https://bugs.launchpad.net/calibre/+bug/2026609 |

 You may be mistaken. I can confirm I have "backup" cover thumbnails dating back to 2020 (when the copying workaround feature was implemented) in the folder, representing books long removed from the device. | |

			In that case, delete the thumbnails and plug your Kindle back into calibre and see if that directory with thumbnails for just what's on your Kindle.

			How can I reproduce the disappearing thumbnail issue? I'd like to test an alternative approach to having to plugin after sync. So far I have been unable to get thumbnails to disappear. |
